Do Dogs Have a Color Preference?

Intermediate Division

Animal Science

Rebecca Grace McGarrh Grade 5 John Nowlin Elementary IN-AS-006

The purpose of the experiment was to determine if a dog was presented with colors, would they have a preference of which to choose. Two different dogs where presented with varying colors of paper. Each dog was encourage to choose a color that, disguised under each paper was a treat. Each time the dog would be allowed to choose ten times. This was repeated three times, but the papers were arranged differently each time. The data was then analyzed and it was determined that on average, the dogs would choose blue or yellow. The conclusion aligns with the fact that dogs can only see a limited range of color.

Whatâ&#x20AC;&#x2122;s in a Name?

Intermediate Division

Behavioral & Social Science Hannah Hinkle Grade 5 Home School IN-BE-001

Sometimes it seems that people are eating too much junk food and not enough healthy food. Why? It is hypothesized that if the food has a heathy name then people will like it less. Three snacks were made using a healthy recipe. Each snack was split into two batches and given a healthy name and a regular name. Subjects were then asked to taste and immediately rate each of the snacks on a 0-10 scale. Each category of snack (brownie, drink, popcorn) was considered one test, making a total of three tests. In reality the snacks were the same. Both brownies were the same, the popcorn was the same and the juice boxes were the same. Only the name was different. The data showed that the people liked the heathy named food more with an average rating of 7.5, compared to an average rating of 6.5 for the food with a regular name. The data collected does not support the hypothesis.

Super Stress Balls Intermediate Division

Behavioral & Social Science Lilly Pfaltzgraff Abby Sosbee Brooklyn Jeffries Grade 5 Home School IN-BE-003-T

Our project's purpose was to create a stress ball to help relieve peoples stress. Our hypothesis was that the instant snow and shaving cream stress ball will feel the best and relieve the most stress. The procedure involved us gathering our human volunteers and testing out our stress balls. We covered their eyes so they could base it off the touch and feel of the balloons, not the look. In our results, 50% of our human volunteers chose the pearl, water, and glitter stress ball as their favorite. We learned that our project was more based on personal opinion because everybody stresses and manages it in different ways. We tried to find a way to relieve peoples stress because itâ&#x20AC;&#x2122;s harmful to the body.

Emotional Rollercoaster

Intermediate Division

Behavioral & Social Science Fields Floersch Grade 5 John Nowlin Elementary IN-BE-008

The purpose of this experiment is to test my hypothesis that we are in control of how we feel, both mentally and physically. I believe there are four primary factors that affect our emotional and physical health and happiness; Diet, Sleep, Electronic Use, and Activity Level. My family participated in a 3-week study consisting of 2 phases: (Phase 1) Practicing Unhealthy Habits and (Phase 2) Practicing Unhealthy Habits. Collectively, my family recorded over 200 data samples in the 3 week period. I took the data points and identified averages of 1) Emotional Ratings, 2) Physical Ratings, 3) Sleep Duration, 4) Activity Level for each family member in each Phase. By identifying averages for each person across each Phase, I was able to compare ratings and changes between phases. Evaluation of the data revealed partially conclusive results. My two brother's data points showed inconclusive results. Me, my Mom and my Dad's ratings, both physically and emotionally, aligned with my hypothesis. We felt better with more sleep, more activity, a healthier diet and limited electronic use. I plan to run a longer test and improve my data gathering survey to test how in control we really are (or aren't).

A Study of Acts of Kindness & the Impact on Mood

Intermediate Division

Behavioral & Social Science Hayden Hughes Grade 5 John Nowlin Elementary IN-BE-009

Sometimes people randomly or purposely perform acts of kindness. The purpose of this experiment is to determine if performing an act of kindness impacts the mood of the person doing the kind act. It is hypothesized that if a person does an act of kindness their mood will improve. Ten people recently did acts of kindness for my dad after he had a major surgery. After they performed the act of kindness, I asked each person how they felt before doing the act of kindness and if their mood changed after performing the act of kindness. Individuals were asked to rate their mood before doing the act of kindness, on a scale of 1-10, with 1 being extremely sad and 10 being extremely happy. They were also asked to rate their mood after performing the act of kindness, using the same scale. The average mood rating of the participants before performing their act of kindness was 6 and the average mood rating after the act of kindness was 9 which shows my hypothesis was supported.

Think Fast

Intermediate Division

Behavioral & Social Science Dylan Seidler Trent Bechtel Grade 5 Prairie Creek Elementary IN-BE-015-T

Our experiment was called Think Fast. Our problem was figuring out if the older you are, will your age affect your reaction time. Our hypothesis was if a person is in an older age group then their reaction time will be slower because they experienced physical changes in nerve fibers that slowed down the speed of conduction in their body and the parts of the brain involved in motor control lost cells over time. We had the person sit in the chair and we held the ruler at the 0 inch mark in between their fingers. Then, we dropped the ruler at a random time. If they caught the ruler we would write it down on a piece of paper, if they didn't then we wouldn’t record it. We did this four times for each person we gathered. We found that a person’s reaction time that was in an older age group was actually faster than the people in the younger age group. In conclusion, we found that a person’s age does not affect their reaction time. Our hypothesis was rejected because we thought that a person’s age would affect their reaction time but it didn’t.

The Rhythm of My Heart Rate Intermediate Division

Behavioral & Social Science Perri Wagner Grade 5 Prairie Creek Elementary IN-BE-0016

My experiment was called Rhythm of my Heart Rate. My problem was figuring out if the food we ate affected our heart rate. My hypothesis was, “different foods could affect your heart rate if it has too much sugar or caffeine in it.” For my tests, I used dark chocolate and black tea. I would first take 4 days to find a baseline heart rate. My first test was to eat 2 bars of chocolate and then rested for an hour and then took my heart rate. My next test, I drank ½ cup of black tea and followed the same one hour timeline and then took my heart rate to see if anything changed from my baseline heart rate.

Chemical Energy

Battle of the Batteries

Intermediate Division

Chemical Energy Elsie Casanova Grade 5 Prairie Creek Elementary IN-CE-006

My problem was figuring out if a Duracell or Energizer battery lasts longer. My hypothesis was, if I change the battery in a headlamp from Duracell to Energizer then I think Duracell will last longer. To test this, I used 20 AAA Duracell batteries, 20 AAA Energizer batteries, and a headlamp. I put the batteries in the headlamp, then turned it on and recorded how long it was on. I did this 10 times with each battery brand. Energizer batteries lasted longer than Duracell batteries. In conclusion, I found that Energizer batteries last longer. My hypothesis was rejected, because I thought Duracell batteries would last longer than Energizer. Nine out of the ten trials Energizer won.

Potato Power

Intermediate Division

Chemical Energy Andrew Ross Jack Kirby Grade 5 St. Andrew the Apostle IN-CSE-001-T

Our project was testing if a potato battery has enough energy to power a small toy car. We thought that a potato battery would not power a small toy car because it would not produce enough volts of electricity. We researched the creator of the potato battery and the amount of energy normal potatoes produce. Our procedure was, first, we chose a potato . Then, we boiled the potato in 210* F water for 8 minutes. Next, we put the zinc and copper strips in the potato. After that, we attached the wire clips and used a multimeter to measure the volts. Then, we wired the potatoes to the car . Finally, If the amount of energy in the potato battery matches the amount of energy needed in the small toy car, our theory is proved wrong. Potato batteries work because chemicals in zinc and copper react and make energy, the energy flows through the potato since it can act as an electrolyte that allows energy to flow freely through it. Our result was that we failed to power the car, but we made a circuit of potatoes and attached it to an LED light and powered it.

Alexis Howard Hunter Placke Makenzie Thurman

Grade 5

Spring Hill Elementary IN-CH-003-T

Coffee drinkers want to keep their coffee at warmer temperatures. Different types of insulators have different impacts on the temperature that coffee is kept at. It is hypothesized that saran wrap will keep the coffee temperature the warmest for the longest amount of time. Four different types of insulators were tested. The types were saran wrap, cotton, tin foil, and Styrofoam. Coffee was poured into four cups, each with a different type of insulator. The temperature of the coffee was measured before being poured. After each increment of ten minutes, up to forty minutes, the temperatures were measured and documented. The data showed that the saran wrap kept the warmest across the forty minutes. The tin foil was the next best at keeping the temperature, followed by cotton and Styrofoam. The data tends to support the hypothesis.

Fabric Factory

Intermediate Division

Chemistry

Kylee Tillery Haley Clark Grade 5 Spring Hill Elementary IN-CH-004-T

The title of our project is the Fabric Factory, the purpose of our project is to figure out which fabric (rayon, polyester, cotton, and mixed blend) dyes the best is different temperature (40 degrees, 70 degrees, and 160 degrees) using red kool aid. Our hypothesis is that cotton will dye the best in the 160 degree water. Our procedure consists of making our three by three fabric squares, putting them in the 160 degree, 70 degree and 40 degree water. We put one of each kind of fabric square in the mason jars for twenty minutes. Then we let them dry overnight on paper towels. The hypothesis was wrong. Instead of the cotton in 160 degree water, the mixed blend was the darkest with all the temperatures. We learned that if you want to make the dyeing process more efficient you should dye it using boiling water.

Rainbow Snow Growth

Intermediate Division

Chemistry

Julia Forgrave Grade 5 Prairie Creek Elementary IN-CH-012

The purpose of the experiment was to investigate the effect of temperature of water on time for fake snow growth. Well hot or cold water make rainbow snow grow faster? if the temperature of water is changed then hot water will grow biggest fake snow faster. Step one: but 6 tsp in a clear cup. Step two: heat up your hot water (200) and cool up your cold water (20). Step three: then color your water with color die. Step four: get your timer and pour your water in the fake snow. The major finding of the experiment were as following: hot water averaged 9.6 & cold water average 14.9 the data supported the hypothesis that stated, if the temp. of water is changed, then hot water will grow the fake snow the fastest. An explanation of my major is because hot water makes stuff expand faster then cold water.

Candle Color and Burning Time

Intermediate Division

Chemistry

Abuchi Ikpeama Grade 5 Conn-West Elementary IN-CH-013

The purpose of the experiment was to investigate the effect of candle color on melting time. Which candle color melts the fastest? If Different colored candles are burnt then green will melt faster than white. Light the candle. Set a timer. Wait until the candle melts all the way. Record the time in your journal. Repeat steps 13 for a total of three trials. Repeat steps 1-4 with the other color of candle. As the color of the candles was changed from green to white, the melting time changed it was found that green melted the fastest than white. The major findings of the experiment were As follows: for each average the green candle took 144.6 min to melt , and the white candle took 251 min to melt. The data did support the hypothesis that stated that green candles will melt faster than the white candles. An explanation of my major finding is that green candles melted faster because they had more chemicals.

Methods for Melting Ice

Intermediate Division

Chemistry

Ayanna January Grade 5 Conn-West Elementary IN-CH-014

The purpose of the experiment was to investigate the effect of different types of salt on ice. Which salt melts ice the quickest? I think sea salt will melt faster because it might have more stuff in it to melt faster. Fill up ice trays with water and place them in the freezer. Measure out Â˝ cups of sea salt rock salt table salt. Place the ice cube in the bowl and pour sea salt on top of the ice cube time seconds how long it takes the ice to melt record in your data table. Repeat the testing a total of 4 times with sea salt. Repeat steps 1-4 using table salt and sea salt and rock salt. As the type of salt was changed from sea salt to rock salt to table salt the melting time of ice also changed. It was found that rock salt melts ice faster than sea salt and table salt. The major findings of the experiment where as follows for melting ice average sea salt was used 34sec rock salt 38sec and table salt 34sec the data did not support the hypothesis that stated rock or table salt an explanation of my major finding is why sea salt went faster than rock salt and table salt cause we added a tiny bit more.

Skittles Dissolving Time

Intermediate Division

Chemistry

Fatima Rodriguez Grade 5 Conn-West Elementary IN-CH-015

The purpose of the experiment was to investigate the effect of liquids on skittle dissolving time. Which liquid dissolves the color coating of a skittle the fastest? If you put Vinegar in a cup of skittles ,The skittles will dissolve faster than Sprite and Water. Place skittles and separate them individually in the rainbow. order against the rim of the plate(equal distance). Add about 1cup of Vinegar in a plastic cup and wait for the reaction. In another cup add 1cup of room Warm water and wait for the reaction. Add 1cup of Sprite in another cup, then wait for a reaction. Lastly, use a timer and see which liquid dissolves a Skittle the fastest! As the type of liquid was changed from Vinegar, Sprite, and Water, the dissolving time varied. Vinegar took 170seconds,Sprite took 184 seconds, and water took 138 seconds. The major findings of the experiment were as for Vinegar I got 170 average, for sprite I got 184 average, and for water I got 138 average .The data did not support the hypothesis that stated. If you put Vinegar in a cup with a skittle in it, The skittles will dissolve faster than water and sprite. An explanation of my major finding is that Sprite dissolved the skittle the fastest.

Soda Staining Teeth

Intermediate Division

Chemistry

Mackinzee Vaughn Grade 5 Conn-West Elementary IN-CH-016

The purpose of the experiment was to investigate the effect of how can coke or pepsi can stan the most on an egg . Does coke or pepsi affect the amount of staining on the egg? if the type of pop is changed, then coke will stain the egg shell the most. Get ingredients. Pour 1 cup of Pepsi into six classic cups and the same with the coke. Label and number each cup Coke or Pepsi. Place 1 egg in each cup. Leave the egg in the pop for one week. Remove the eggs and record the amount of staining in your journal. As the type of soda was changed, the Coca-Cola stained the eggs slightly more than the Pepsi. The major findings of the experiment were As coke stand slightly more than pepsi. The data did support the hypothesis that stated the Coca-Cola would stain more than the Pepsi. An explanation of my major finding is. It was because pepsi just dizoved it kinda.

Oobleck & Eggs

Intermediate Division

Chemistry

Macy Riddle Grade 5 John Nowlin Elementary IN-CH-018

Sometimes people need to create objects that protect other objects by absorbing the energy that is caused by a force. It is hypothesized that the oobleck will absorb the energy caused by the fall and protect some eggs from cracking. I dropped five eggs from different heights, into the same amount of oobleck, made with the same consistency. The data showed that from a height of one foot and four feet the eggs survived, the others, dropped from two, three, and five feet did not survive. The data supports the hypothesis.

Smell You Later

Intermediate Division

Chemistry

Devlen Moore Grade 5 John Nowlin Elementary IN-CH-026

Some people live very busy and active lives. Becoming sweaty and smelly can be an inconvenience, and you want a deodorant that can last longer and keep you sweat free. Many products claim to last a full 48 hours, keeping you smelling clean and fresh. The hypothesis is that the Dove brand for men will work the best and the Dove brand for women will work as well as the Dove for men. Four popular brands were tested: Axe, Dove for men, Dove for women, and Old Spice. Three of the products are formulated for men and one for female to compare the results. Each product was tested every 48 hours. This procedure was done for ten trials total. Five of the trials were done with regular, day to day activity. The other five trials were done with an extra 30 minutes of physical activity done daily. Although the data revealed the Dove for men and women performed almost the same, they were both low performing. The data showed only the Old Spice deodorant lived up to the advertisement. The data did not support the hypothesis.

Homemade vs. Commercial pH Paper

Intermediate Division

Chemistry

Veronica Kish Grade 5 Our Lady of the Presentation IN-CH-027

The pH scale is discussed in this project. In science the acidity and alkalinity of solutions can be measured. PH indicator paper can be created at home using red cabbage dye solution and lab grade filter paper. The homemade pH paper can be used to measure the acidity or alkalinity of different household solutions. Results of the homemade pH paper can be validated by using a commercial grade pH paper. Is homemade pH paper as reliable as commercial pH paper? It was found that the homemade pH paper can be a good indicator to find an acid or a base solution. Various solutions that are used every day around the house were tested. After testing the solutions with the homemade pH paper, the commercial pH paper was tested on the same solutions to verify with a numeric result.

Pop! Pop! Fizz! Fizz!

Intermediate Division

Chemistry

Aliza Kester Grade 5 John Nowlin Elementary IN-CH-036

People often have pain and stomach issues and want fast relief. I hypothesize that if the surface area of an Alka-Seltzer tablet is increased, then the time it takes to dissolve will decrease. Three glasses were filled with water. Whole tablets, two half tablets, and crushed tablets were dissolved in water to see which would dissolve faster giving someone faster relief. The data showed that the powder dissolved at an average of 22.63 seconds which is faster than the whole tablet which dissolved at an average of 50.61 seconds the data supports the hypothesis.

Thermochromic Slime Vs. Liquid Crystal Square

Intermediate Division

Chemistry

Hosannah Wellman Grade 5 John Nowlin Elementary IN-CH-038

Sometimes people need to know how hot something is to make sure it is safe for them, it is hypothesized that thermochromic slime will heat up faster and stronger than liquid crystals. Two batches of thermochromic slime were made. Liquid crystal squares were obtained from an outside source. The slime and liquid crystal were tested against six different items, each at different temperatures. The data showed that the liquid crystal reacted faster, and at a wider range of temperatures. The data tends to go against the hypothesis.

Bounce

Intermediate Division

Chemistry Natalie Rice Elizabeth Olson Grade 5 Prairie Creek Elementary IN-CH-040-T

Our hypothesis is that if we put helium in an empty soccer ball then it will bounce higher than ones with air in it, and our hypothesis was accurate, the ball with all helium bounced the highest at an average of nearly 40 inches high each bounce. First, we gathered our materials. Then we made 4 feet marks on the wall with the inches in between each foot. We emptied all the soccer balls so we could fill them up with helium, air, and a little bit of both. We weighed the balls to see if they were all the same when we took the air out, they all weighed the same at 366 grams We filled up ball A with all helium, and it lost 2 grams when we did so. We filled ball B which was half air half helium, so when we put helium in it we made sure that it only lost 1 gram and then we put air in it trying to bring it back to 366 grams. We added air to ball C and it gained 1 gram. We dropped the ball at 5 feet high while filming, so we could see how high it bounced, and continued this process multiple times to the different balls. We wrote down all the information. We found the average of how high each ball bounced. We and made a graph of all our data.

Drown the Brown

Intermediate Division

Chemistry Abby Stevens Juna Finks Danin Hokanson Grade 5 Wolf Springs Elementary IN-CH-042-T

A common problem when packing apples for lunch is that, when cut, they easily turn brown. It is hypothesized that lemon juice will stop the oxidation better than any other common liquid. Four apples were sliced and placed into six cups of different liquids (lemon juice, water, water and honey, pineapple juice, sprite, and white grape juice), and a control group for comparison. They were left in the liquids for 15 minutes. Observations were then made at 15 minutes, 30 minuets, one hour, and 1 1/2 hour after removal. The observations were visual and used a ranking of 1-6. Lemon juice was the most effective in keeping the apple's flesh from browning. White grape juice, pineapple juice, water, water and honey mixture, and Sprite followed in the ranking of 2-6 All were more effective than leaving the apple out of liquid, as shown by the control group.

Baking Soda vs. Baking Powder in Cupcakes

Intermediate Division

Chemistry

Caitlin Winebrenner Grade 5 Prairie Creek Elementary IN-CH-043

If you pour regular soda out of a newly opened soda bottle, then it will produce more fizz than diet soda because there is more sodium in regular soda than diet soda and the sodium helps make some of the fizz. The title of our project is Fizz-Tastic Sodas. Our question is “When you pour soda out of a newly opened soda bottle, which produces more fizz: Regular, or Diet soda?” Our results were interesting, as the Diet Cola should have fizzed more, but it hadn’t. It should have fizzed more than the regular because there is more CO2 that is released in Diet Cola. In conclusion, the data shows that the regular fizzed more than the diet. The data allowed us to support and accept the hypothesis, instead of it getting refuted and rejected. For our procedure, take the regular Cola, and pour it into one cup. Quickly place your thumb where the foam stopped. Take your sharpie and mark where your thumb was and write what number trial it is (1, 2, 3, 4, or 5th Trial test). Empty soda from the glass and repeat steps 1-3 four more times so you have 5 trials recorded. Repeat steps 1-4 with Diet Cola. When you open a can or bottle of soda and pour it into a glass, foam begins to form quickly, and can spill over the edge as we experienced in our experiment. In our experiment we measured the foam on top of the soda.

How Does the Cookie Crumble?

Intermediate Division

Chemistry

Jazlyn Zuniga Grade 5 Prairie Creek Elementary IN-CH-044

How does your cookie crumble? My procedure is to follow the cookie recipe using melted butter, then again for room temperature butter, then a third time for cold butter. Repeat each recipe 4 times to give each variable 4 trials. My hypothesis is that If I increase the temperature of the butter in a chocolate chip cookie, then the cookie will become softer, because butter is a liquid fat comparable to vegetable oil, providing the cookies with richness and softness but not contributing to its structure. My problem is does the temperature of butter affect the softness of a chocolate chip cookie? My results was that the regular butter made the cookie the softest. My hypothesis was rejected. The data showed means that the regular butter made my cookies the softest and the melted butter made the cookies the hardest. In the cookies with the melted butter the butter absorbed all the other ingredients and made them into a watery texture. In the cookies with the soft butter, the butter did the same sort of thing. In the regular butter it made a blob of ingredients.

Homemade Putty

Intermediate Division

Chemistry Tinly Merryman McKenzie Riffle Grade 5 Prairie Creek Elementary IN-CH-045-T

The problem of our investigation was that if putty dried faster with salt added in, sugar added in, or by just following the recipe. We were curious if what you add into putty changes the outcome of when itâ&#x20AC;&#x2122;s going to dry out. Our hypothesis was that the putty with salt added in was going to dry out first and the putty with sugar added in was going to be the second to dry out. Let the putties sit out for twenty-one hours and five minutes, then write down the data. The results support our hypothesis because we thought that the putty with salt would be the worst and dry out faster. But we were also wrong because we thought the putty with sugar would dry out the second fastest when it was really the last one to dry out and was the best of all the trials.

Fizz-Tastic Soda

Intermediate Division

Chemistry McKenna Swanson Quinn Hubbard Grade 5 Prairie Creek Elementary IN-CH-046-T

If you pour regular soda out of a newly opened soda bottle, then it will produce more fizz than diet soda because there is more sodium in regular soda than diet soda and the sodium helps make some of the fizz. The title of our project is Fizz-Tastic Sodas. Our question is “When you pour soda out of a newly opened soda bottle, which produces more fizz: Regular, or Diet soda?” Our results were interesting, as the Diet Cola should have fizzed more, but it hadn’t.

In our experiment we measured the foam on top of the soda.

Sweet Science

Intermediate Division

Chemistry

Avery Gallagher Grade 5 Prairie Creek Elementary IN-CH-047

My experiment was called Sweet Science. My problem was figuring out if the type of sugar has an effect on the rise of a cupcake when baking cupcakes. My hypothesis was if I replace the exact amount of common white granulated sugar in a cupcake recipe with powdered sugar, then the cupcakes will not rise as much as expected because of the effect of the cornstarch mixed in the prepackaged powder sugar. For my experiment I used powdered sugar, white granulated sugar, vanilla extract, 2% milk, unsalted butter, flour, and eggs. First, I made four separate batches of batter using white granulated sugar. Then I used the exact same recipe, but I replaced the white granulated sugar with powdered sugar. Each batch had enough batter for exactly five cupcakes. I took pictures while the cupcakes were baking. I also took pictures after they cooled. Once the cupcakes were completely cooled I used a ruler to measure the rise of each cupcake in centimeters. In the end I found out that my hypothesis was correct. The powdered sugar cupcakes didnâ&#x20AC;&#x2122;t rise as much as the regular white granulated sugar cupcakes. In all four batches, the cupcakes with white granulated sugar had the highest average rise.

The Mystery of Salt and Water

Intermediate Division

Chemistry

Reis Martin Grade 5 Prairie Creek Elementary IN-CH-048

The title of my project is “The Mystery of Salt and Water.” The hypothesis I wrote was; If you increase the amount of salt in water then the boiling point will increase because salt slows down the water molecules and to boil water the water molecules have to have enough speed. My procedure told them to boil water, test the temperature, and dump it out. Repeat this but add 1 tablespoon of salt before boiling the water. Repeat that process again but instead of 1 tablespoon of salt add two tablespoons of salt. My problem is; does the amount of salt added to water increase it’s boiling point? My results were if you add 0 tablespoons of salt the boiling point will be 210-211. If you add 1 tablespoon of salt the boiling point will be 212 and if you add 2 tablespoons of salt the boiling point will be 214. The data I gathered shows that the more salt you add the more the boiling point increases. My data went with my hypothesis and if you add salt the water’s boiling point will increase.

Chocolate Chip Cookies

Intermediate Division

Chemistry Alexis Hinds Madison Morris Grade 5 Prairie Creek Elementary IN-CH-049-T

In this experiment we tested how different chocolate chips impact the Taste, Aroma, and Texture of chocolate chip cookies. Our hypothesis is how do different brands of chocolate chips impact the taste? So we know what kind of chocolate chip cookies to make. Which type of chocolate chip flavor satisfies people. Ingredients. 1 cup salted butter softened. 1 cup white granulated sugar. 1 cup light brown sugar packed. 2 tsp pure vanilla extract. 2 large eggs. 3 cups allpurpose flour. 1 tsp of baking soda. Â˝ tsp of baking powder.

Whereâ&#x20AC;&#x2122;d It Go? The problem is, I wanted to know which type of egg is stronger with no shell hardboiled or Raw.

Intermediate Division

Chemistry

Benjamin McConnaughey Grade 5 Prairie Creek Elementary IN-CH-050

The hypothesis is, if I soak the hard boiled egg in vinegar then It will bounce most from 3 inches. A brief procedure, I soaked a raw egg and a hard boiled egg in vinegar. Then I dropped both eggs from three inches and compared the results. The hard-boiled egg took more drops than the raw egg to come out of the casi.

Which Liquid Freezes Fastest?

Intermediate Division

Chemistry

David Link Grade 5 Prairie Creek Elementary IN-CH-051

My experiment was called, which liquid freezes the fastest? My problem was which liquid freezes the fastest carbonated or noncarbonated? My hypothesis is carbonated liquids will freeze faster than non-carbonated liquids because the dissolved gas will help lower the temperature quicker. For this I used milk, juice, diet soda, and soda. I put each liquid in the freezer with the probe in the liquid until it reaches 32 Â°F. I timed how long each trial took and put it in a graph see page 10. Milk froze the fastest out of all the liquids with diet soda coming in a close second almost every time. My hypothesis was not correct I thought the carbonated gas in carbonated liquids would freeze the liquid faster.

How Sweet Is The Treat?

Intermediate Division

Chemistry Luciana Silvio Victoria Cuezze Grade 5 St. Andrew the Apostle

IN-CH-052-T

For our science fair project we explored how the amount of sugar in homemade ice cream affects how freezes? We chose this project because we like baking and we love ice cream! We thought it would be fun to incorporate ice cream with our science fair project! Our hypothesis was the more sugar you add the longer it takes to freeze. We think that is because the more sugar we add the sugar molecules will dissolve and that makes the temperature decrease, then the sugar will eventually be captured by the ice. We researched a typical freezing point, who made the first homemade ice cream ,how the sugar affects your body, and what different ingredients affect the way it freezes. Our steps to do the project were to make 4 batches of ice cream. After we separate the mixture into 4 bowls we will add ¼ cup of sugar into one bowl. In another bowl we will add ½ cup of sugar. Then in the third bowl we will add ⅔ cups of sugar in the last bowl we will add 1 cup of sugar. We then put one batch of ice cream at a time in the ice cream mixture then we left the ice cream batches in the freezer. We checked it at the 30 minute mark,1 hour mark, the 2 hour mark, and overnight. We realized that the less sugar it does not freeze the most sugar doesn't freeze the ½ and ⅔ cups of sugar worked the best.

Color Flowers

Intermediate Division

Chemistry Chloe Kreimendahl Taylor Wedel Grade 5 Prairie Creek Elementary IN-CH-053-T

Valentineâ&#x20AC;&#x2122;s Day is just around the corner, and florists are always coming up with new ways to make flowers look unique and pretty. We have seen flowers that are all different colors, and were wondering how they were made to look that way. We wanted to create an experiment where we could test out which flower could absorb the most color. We used three different types of flowers for our experiment: rose, daisy and a carnation. In the end, we wanted to know- which flower will absorb the most blue food dye? If we put a rose into blue dyed water, then the rose will absorb the most color. Gather materials needed for experiment. This includes 3 different white flowers, 1 vase, blue food dye, and 2 cups of water. We numbered the flowers. First we put the 3 flowers in a vase. Then we put 2 cups of water in the vase. After that, we put 5 drops of blue dye in the vase. We waited 4 days to see our results.

Glue Effect

Chemistry Kaitlyn Shipley Madeline Weaver Grade 5 Prairie Creek Elementary IN-CH-057-T

The title is... Will Glue Effect How Far Slime Stretches? The problem is does glue affect how far slime stretches. Are hypothesis slime with clear glue would stretch farther than glitter glue, white school glue, and normal color changing glue because there is nothing to stop it like glitter. The procedure is that we made four batches of slime all with different glue. Then we laid a tape measure on the floor and stretched the slime next to it. The results are that White on average stretched 106 in. the clear 102.6 in. the glitter 207.6 in. The blue glue stretched 129.3 in. The conclusion was that the glitter glue stretched farthest the blue Glue. Then the white. Then the clear.

The purpose of the experiment was to investigate the effect of the surfaces on heat absorption. How does a surface affect the rate it is warmed? If different surfaces get heated then water is going to get heated more than soil and sand. As the type of surfaces changed the surfaces get heated up the sand, water, and soil temperatures changed at different rates with sand averaging 23.3 degrees Fahrenheit, the water averaging 20 degrees Fahrenheit, and soil averaging 43.6 degrees Fahrenheit after one hour of exposure to a light bulb. The major findings of the experiment were as follows: soil, water, and sand where heated up they made different heated numbers and soil had a temperature of 23.3 on average, while water had a temperature of 20 on average, and sand had a temperature of 43.6 on average. The data did not support the hypothesis that stated water would get heated up more than soil and sand. An explanation of my major finding is that soil gets heated more because the lamp was putting so much heat on it until it turned into dust.

The Effect of the Concentration of Microplastic in Water on the Amount of Microplastic Integrated into Palaemonetes paludosus Microplastics are well documented in oceanic systems and are beginning to be studied in freshwater systems. Freshwater ghost shrimp (Palaemonetes paludosus) will be given certain concentrations of microplastics in freshwater. Ghost shrimp will be observed for the method by which the microplastics enter the ghost shrimp. The microplastic particles that enter the ghost shrimp will be measured using nile red dye to fluoresce the microplastic.

The purpose of the experiment was to find new ways to melt the ice on the roads since salt is harmful to the environment. We poured 1/2 cup of 5 different substances in a bowl and added a standard sized ice cube. We also had a control bowl which was an ice cube by itself. Then we timed how long it took to melt the ice. We used beet,pickle and lemon juice along with saltwater and Sprite. The saltwater melted ice the fastest. We concluded that further testing should be done to see if a mixture of substances could be used to cut down on damage to the environment.

Sometimes people need to create an energy source and circuits. In order to do that they need to understand what energy can and cannot travel through. It is hypothesized that saltwater will produce more electricity than a lemon or potato because it has more ions. I passed energy, using a volt meter, to a lemon, a potato and salt water separately and tracked the data, measured in millivolts. The lemon was able to pass more millivolts. The data did not support the hypothesis.

The faster a BMX rider can get out of the gate, the better the chances of them winning the race. It is hypothesized that the higher a BMX rider's weight is, the faster their speed will be rolling out of the gate. Using a Pro-Start Gate with an automatic timer, four riders were weighed and using the same BMX bike, rolled 30 feed down a 15-degree slope for time. The procedure was done for three trials per rider. The data showed that the weight of the rider did not affect their speed rolling out of the gate.

I did this experiment to figure out if the amount of time it took for batteries to die would change if the batteries were put in different places. I experimented this by putting batteries in different habitats-A freezer, by a heater, and in room temperature. The time it took for the batteries to die did change in different places. It did take that long for the heater batteries to die. But it took a lot of time for the room temperature batteries. The freezer batteries were in between. My hypothesis was supported. The room temperature batteries took the longest amount of time to die.

Sometimes powerline builders need to know what objects are conductors or insulators. It is hypothesized that a nail would conduct more electricity than a chunk of wood. At each trial a circuit was set up and an object placed inside. Each circuit was built the same but with a different object. Each object was tested once and the current flowing through the circuit was measured with a multimeter. This was done nine times in all. The results showed that metal objects conducted the most electricity (0.20 Amps), rusted metal objects conducted slightly less electricity (0.19 Amps), and non-metal objects conducted no electricity (0.00 Amps). The results supported the hypothesis.

Colton Northup Grade 5 Prairie Creek Elementary IN-EE-017

The experiment, Insulating Against Heat will address the problem of what is the best insulator. It is hypothesized that fiberglass insulation will be the best insulator against heat. To test this hypothesis the researcher has selected seven different materials to test in this experiment. Each material was tested by placing the material in a box over a heat lamp and measured the temperature on the surface of each insulation. The results show that the newspaper had the lowest surface temperature out of the seven materials. The fiberglass insulation had the fifth highest surface temperature showing the hypothesis was not validated by the experiment. The researcher has concluded the newspaper was the best insulator of the tested materials.

The purpose of the experiment was to investigate the effect of different bridge materials on bridge strength. Will the materials used affect the strength of the bridge? If different materials are used to build a bridge then popsicle sticks will have the strongest bridge. Once the bridges are made, test out your experiment. As the bridge materials were changed from popsicle sticks to toothpick the strength of the bridge changed with popsicle sticks average of 7 and toothpicks with average of 3. The major findings of the experiment as follows: popsicle sticks averaged 2.3 lbs and toothpicks averaged 1 lb. The data did support the hypothesis.

The purpose of the experiment was to investigate the effect of launch angle on rubber band distance. Does the launch angle affect the distance a rubber band launcher will launch rubber bands? if rubber bands are launched different angles, then 40 degrees will fly farther than 50 degrees and 60 degrees. Sit the rubber band launcher at a nice area were the rubber band can launch as far as it can, and high as it can. Put measuring tape and start from the arm of the rubber band launcher. Bend paper clip it to where itâ&#x20AC;&#x2122;s straight. You sit the arm of the launcher angle to 40 degrees. Stick the paper clip through the two holes. Then pull the rubber band back to 20 cm and let go. Wherever the rubber band lands mark it and record the distance. Repeat steps 1-4 for a total of 3 trials. Repeat steps 1-5 using 50 degrees and 60 degrees. The major findings of the experiment were AS follows: 40 degrees averaged 649.3,50 degrees averaged 494.6 and 60 degrees averaged 511.3. I changed the angle of the launch angle. The data was supported that a rubber band launched a 40 degrees, it will go the farthest.

We did our project to determine which Lunar Lander would have the safest landings on the Moon. We brainstormed design ideas in our notebook. We made the landers with a cup and cardboard platform. Next each student added their own shock absorbing attachments and padding. Then we weighed them, all landers must be under 45 grams to imitate how importance a lightweight lander would actually be in space. We wrote our hypothesis and then did our experiment. We dropped each lander 10 times at each height and recorded that data. We looked at the data and saw one lander was the clear winner which, in turn, disproved our hypothesis. We then modified the best lander and tested it again to further improve our design. It had only 1 unsafe landing. Our final design was the best overall.

If we design a bridge with an x pattern to help support the structure, then that bridge will hold the most pennies and weight. We experimented with the same weight of pennies with different bridges designs such as straight designs, X design, and a zig zag design. Our hypothesis was correct because the X design held the most pennies out of all the structures. From our experiment, we learned that in order for bridges to hold more weight, the design should allow the structure to hold the most weight. We learned that bridges that have a double stacked design are fit to hold the most weight.

We tested the structures and also recorded the data and results. We dropped our structures from the top of a chair and recorded if it broke or not. Hypothesis: If we put a parachute around the red cup and fill it with the cotton balls and drop the egg, it should not break. Our problem is that we have to make structures to protect the egg from breaking. We had to make 3 different structures to protect the egg. Results: For the grapefruit structure we had 3 no breaks and 1 break. For the popsicle stick box we had 2 breaks and 2 no breaks. Finally, we had no breaks with the parachute structure. As a result, the parachute structure was the best to use during an egg drop.

According to the literature, all three authors support that mold grows slower in colder environments. Others wrote that the humidity also plays a role in mold growth. In this science project, I only want to test if the temperature affects mold growth. We sliced up 2 identical pieces of bread and put them in sealed containers and set them at different temperature conditions (refrigerator and room temperature). After every 2 days, we observed when the mold was growing and how many spots there are when the mold shows up. We observed the bread for 7 days. We first observed that the mold appeared on the bread kept at room temperature. After 7 days, the bread in the refrigerator did not show any observable mold. We repeated this experiment 2 more times and the results were the same. All of these experiments support they, yes, mold grows slower in colder temperature.

This experiment is testing how strong different hand sanitizers are by growing bacteria collected from an iPad, and recording which hand sanitizer kills the bacteria best by using a point system to tally how well the hand sanitizer worked. This Is being tested to know which hand sanitizer is the strongest and most reliable. I predict that Purell advanced will work the best, over Up & Up and GermX. I predict this because Up & Up has many main products other than hand sanitizer while, GermX and Purell (advanced) have their main product hand sanitizer. Out of a GermX and Purell, Purell was the easiest to find. My prediction was correct. Purell advanced scored a total of 8, second Germ X with a -6, and thirdly Up and Up with a -7.

My project is What is the dirtiest place in our school. I picked this project because I thought it would be cool to see what germs are in our school. My hypothesis said that I thought the bathrooms and the preschool water fountain were the dirtiest places in the school, because preschoolers forget to wash their hands. I took sterile cotton swabs and swabbed my chosen areas. After I had swabbed all of the areas, I took the petri dishes home. I put a heat source (a space heater) inside the box where the petri dishes were placed, but it was hard to keep a constant temperature between 85 and 100 degrees. The next day, I realized that the space heater would work better outside of the box, because there is more airflow out of the box. The lack of airflow in the box made the space heater shut itself off, because there was no air. After I moved it out of the box, bacteria had started to grow. The bacteria was white when it started growing. Later, I saw brown, orange, and yellow bacteria. During this experiment, I kept monitoring the temperatures with my father's temperature gun. The results said that my hypothesis was halfway correct. The boys bathroom and the sink in the bathroom area were very dirty. Ms. Kim's cleaning cart and Ms. Kettles door handle were even more dirty. I was very surprised with the results.

Sometimes people need to know how many germs your school has. It was hypothesized that the girls’ bathroom would have more germs than the boys’ because there are more girls than boys on the floor. The same items from each bathroom were tested: cold water handle, hot water handle, door handle, and toilet seat. Spores were collected by using a Q-tip to rub against the objects. Then, the contaminated Qtip was rubbed on a petri dish prepared with nutrient agar. The germ spores were grown for two weeks. The data shows that the boys’ bathroom is dirtier than the girls’ bathroom. This conclusion was made by totaling the germ spores in each bathroom. The app “Colony Counter” was used on a tablet to count the colonies. The boys’ cold water handle produced 462 germ spores, the boys hot water handle produced 28 germs spores, the boys door handle produced 23 germ spores, and the boys toilet seat produced 9 germ spores which totals 522 germs spores. The girls bathroom only produced a total of 165 germ spores. The girls cold water produced 42 germ spores, the girls hot water produced 14 germ spores, the girls door handle produced 24 germ spores, and the girls toilet seat produced 85 germ spores. This proves that the stated hypothesis was wrong.

How Long Does it Take Different Types of Pain Pills to Dissolve in Our Stomach? Intermediate Division

IN-MO-003

People sometimes have the problem of being in pain and need to take pain medication to feel better. The purpose of the experiment was to see which type of pain pill dissolves the fastest and slowest in our stomach. Brand name and generic brand pills were tested. The pills were dissolved in vinegar while being stirred in a KitchenAid counter mixer. The vinegar was 5% acidic (pH about 2.4) which is the same as stomach acid, and the vinegar was heated to about 100 degrees F which is about the same as body temperature. Each pill was tested 3 times, and a stopwatch was used to time how long it took each pill to dissolve. The average of the 3 times was reported as the result. The pill that dissolved the fastest (first) was Tylenol 500mg caplet, in 2.92 minutes; second was Tylenol 500mg rapid release gel cap, in 3.02 minutes; third was Children's Tylenol 160mg chewable tablet, in 5.42 minutes; forth was Best Choice Acetaminophen 500mg caplet, in 5.54 minutes; fifth was Advil 200mg tablet, in 10.35 minutes; sixth was Advil 200mg liqui-gel, in 15.37 minutes; and last to dissolve (seventh) was Equate Ibuprofen 200mg tablet, in 30 minutes, and testing was stopped at 30 minutes because it was still not dissolved. The hypothesis was that the liquid capsule (Advil 200mg liqui-gel) would dissolve the slowest because it has a hard, outer coating, and the results did not support the hypothesis.

It’s a Moldy Mess!

My experiment was called It’s A Moldy Mess! The problem was figuring out how quickly bread molds in different temperatures. My hypothesis was if I put bread in a room temperature place, then it will mold faster than if I put it in a cold place because a room temperature place processes more moisture and that is how mold grows. For this experiment I used white bread, brown bags, and Ziploc bags. I put 4 pieces of bread in 4 separate Ziploc bags and then in 4 separate brown bags and put them in a room temperature space. Then I repeated the same thing except I put the other 4 in the fridge. I figured out that the bread didn’t mold in either temperature, it definitely got stale but there was no mold at all! My hypothesis was incorrect and it didn’t mold in the room temperature place like I expected it too.

Different types of toothpaste have different effects on teeth. We tested different types of toothpaste on cracked eggs to see which were the strongest sealants for teeth over different amounts of time. It is hypothesized that the Colgate Ultra Whitening was going to keep the egg sealed the best. Three types of toothpaste were tested: Colgate Ultra Whitening, Colgate Kids and Crest Kids. Nine eggs were cracked to test the different strengths of sealant over time. In the first round each of the three eggs got a different type of toothpaste and after five minutes they were tested to see how well they sealed. This procedure continued for ten and fifteen minutes as well. The data showed that the Colgate Ultra Whitening was the strongest sealant across all time frames. This data tends to support the hypothesis.

Slime Viscosity

Purpose - how does the type of ingredient change the viscosity of slime. Procedure - Made regular slime with 16 oz clear glue, 1 cup warm water, 3 drops red food coloring & 1 tsp of Borax. For butter slime, used all same ingredients and added 8 oz. of Model Magic Clay. Data/Conclusions - According to the data, the regular slime was stretched further than the butter slime. The regular slime averaged 42 inches when stretched. The butter slime averaged 14 inches when stretched. Therefore, the hypothesis of the regular slime stretching further was correct. Due to the weight or heaviness of the butter slime, it did not stretch as far as the regular slime. The change of the viscosity in the butter slime was due to the added Model Magic Clay, which also affected its weight or heaviness. The regular slime viscosity was thinner because it had less ingredients and did not contain the Model Magic Clay; however, the regular slime was much stickier and harder to handle. Even though the butter slime did not stretch as far, it was less sticky and easier to handle. The Model Magic Clay affected the viscosity and stickiness.

Have you ever wondered if you could transfer water from one cup to another without pouring it yourself? This experiment proves you can do just that by using capillary action to transfer the water into empty cups. This procedure has five tests each for two different volumes of water, 200 mL and 300 mL. The 300 mL tests took the least amount of time, between 10 to 12 hours. The 200 mL tests took the longest, from 14 to 16 hours. The hypothesis was proved to be correct, the amount of water did affect the speed of water transferring through the paper towels.

Fabric Flammability

Intermediate Division

Materials Science Giuliana Ferrara Grade 5 Our Lady of the Presentation IN-MS-019

The purpose of this experiment was to identify what fabric is most flammable, between rayon, cotton, satin, wool or fleece. The hypothesis was that a loosely woven fabric like wool or fleece would be less flame resistant than a tightly woven fabric such as satin or rayon. The experiment was performed by having a fabric suspension system that held the different fabric types and was the target of a propane torch from three different distances away, 1”, 3” and 6”. The independent variables were the different fabric types and the distance of the fabric from the propane torch. The dependent variable was the elapsed time before the fabric ignited. The testing was performed by placing a piece of fabric in the fabric suspension system and lighting the propane torch a set distance away while also starting the stop watch. This was performed for each fabric type at distances of 1”, 3” and 6”. At a distance of 1”, rayon and cotton were quickest to ignite both at 2.41 seconds, satin at 4.61 seconds and wool at 5.06 seconds. At a distance of 3”, rayon was the quickest to ignite at 2.65 seconds, cotton was a close second at 3.65 seconds and wool ignited at 8.69 seconds. Fleece was determined to be the most flame resistant fabric given it never ignited. Based upon the results, the hypothesis was not supported. Loosely woven fabrics tend to be more flame resistant when exposed to fire and therefore a safer fabric to be worn.

When I'm playing basketball on courts made from different materials, I notice my ball can bounce differently. Will the surface that basketball court floors are made from effect how high a basketball will bounce? Which surface will make the basketball bounce the highest? This experiment tested four different basketball court surfaces. A basketball was dropped on each flooring and the height that the ball bounced was recorded. The average height the ball reached on Concrete flooring was 22.4inches. The average height the ball reached on Asphalt flooring was 21.78 inches. The average height the ball reached on Wood flooring was 22.13 inches. The average height the ball reached on Rubber flooring was 23.32 inches. It was found that different surfaces do make a difference on how high a ball reaches when bounced. The surface that makes the ball bounce the highest was the rubber court.
