CHM 110 Wk 1 - States of Matter: Basics Simulation 1. 2. 3. 4. 5. 6.
7.
Visit the States of Matter: Basics Simulation, and follow these steps: Click States from the Home screen. From the Atoms & Molecules Menu on the top right, select Water. Select the Solid button. Observe the atomic structure of water as a solid. Note the reading on the thermometer near the top of the container. Select the Liquid button. Observe the atomic structure of water as a liquid. Note the reading on the thermometer near the top of the container. Select the Gas button. Observe the atomic structure of the water as a gas. Note the reading on the thermometer near the top of the container. Cool the container by clicking and holding the slider to “Cool,” under the container. Continue to cool the sample until the thermometer reaches the lowest possible reading. Observe the lowest reading and pay attention to the change in motion of the molecules as you do this. Heat the container by clicking and holding the slider to “Heat.” Continue to heat the sample until the thermometer reaches the highest possible reading. Observe the highest reading and pay attention to the change in motion of the molecules as you do this. Following completion of the simulation, write a 260- to 350-word response answering the following: What did you do during the simulation? Briefly describe. What did you observe?
What do your observations teach you about the atomic nature of matter? What additional questions does this make you wonder about related to the atomic nature of matter? In your response, include some of the new vocabulary introduced in this week’s reading, such as: Matter Atoms Molecules Solid Liquid Gas Mixture Mass Law of Conservation of Mass Temperature Heating Submit your assignment.

http://www.uopstudy.com/ CHM 110 Wk 2 - Energy Forms and Changes Simulation 1. 2.
3. 4. 5. 6. 7.
Visit the Energy Forms and Changes Simulation, and follow these steps: Click Intro from the Home Screen. In this simulation you have 4 substances: iron, brick, water, and olive oil. You have 2 heating plates to heat those substances. You also have thermometers you can drag and drop on various substances to measure temperature. Drag and drop a substance (iron, brick, water, or olive oil) on top of the hot plate. Drag and drop a thermometer on top of each substance. Heat each substance and cool each substance. Observe the changes in the thermometer. Repeat Step 2 until you have heated, cooled, and measured each substance. Click Energy Symbols at the top of the screen. Little squares with the letter E will appear in each substance.
8.
Repeat heating and cooling each substance as you did in Steps 2-4. Make sure you heat to as hot as the substance will allow and cool to as cold as the substance will allow. This time observe what happens to the Energy Symbols. Pay attention to similarities and differences between the substances. Following completion of the simulation, write a 260-350-word response answering the following: What did you do during the simulation? Briefly describe. What did you observe? What do your observations teach you about the storage and transfer of energy? What additional questions does this make you wonder about related to the storage and transfer of energy? In your response, include some of the new vocabulary introduced in this week’s reading, such as: Energy Kinetic energy Potential energy Chemical energy Endothermic Exothermic Heating Temperature First law of thermodynamics Second law of thermodynamics Liquid Solid Density Submit your assignment.

http://www.uopstudy.com/ CHM 110 Wk 3 - Acid-Base Solutions Simulation Visit the Acid-Base Solutions Simulation, and follow these steps: 1. Click My Solution from the Home Screen. 2. Above the container, to the right, there is a pH meter. Drag and drop it into the solution to obtain an initial measurement. The initial reading should have a pH of 4.50.
3.
Increase and decrease the arrows beneath Initial Concentration. Observe what happens to the solution and note how the pH changes. 4. Adjust the Strength of the solution by dragging the slider between “weaker” and “stronger.” Observe what happens to the solution and note how the pH changes. 5. Near the top right of the screen, switch the toggle from “Acid” to “Base.” Repeat your steps and observe what happens.
Following completion of the simulation, write a 260- to 350-word response answering the following: What did you do during the simulation? Briefly describe. What did you observe? What do your observations teach you about acids and bases? What additional questions does this make you wonder about related to acids and bases? In your response, include some of the new vocabulary introduced in this week’s reading, such as: Solvent Solute Solution Concentration Acid Base Equilibrium Molecules pH Submit your assignment.

http://www.uopstudy.com/ CHM 110 Wk 4 - Reactants, Products, and Leftovers Simulation Visit the Reactants, Products, and Leftovers Simulation, and follow these steps: 1. Click Sandwiches from the Home Screen.

8.
Review the top of the screen, which shows a recipe for how to make a sandwich. Note that it takes 2 pieces of bread and 1 piece of cheese to make one sandwich. Under the Before Reaction box, near the bottom of the screen, use the arrows to add 2 pieces of bread and 1 piece of cheese; these are called Reactants. Note how one completed sandwich, with no leftover ingredients appears in the After Reaction box. This is because you had just enough ingredients to complete the recipe with no leftovers. Begin adding more Reactants (same as Step 3). Note what happens to the Products and Leftovers in the After Reaction box. Continue to make changes until you notice and feel confident about the patterns you are seeing. Near the top right of the screen, change the recipe to Meat and Cheese. Notice the sandwich recipe becomes more complicated. Repeat the steps you did for the previous recipe and see what patterns you notice. Click Molecules at the bottom center of the page to switch the simulation view. Chemical reactions work the same way as your sandwich making exercise. Play with the simulation until you notice patterns. If you would like to test your understanding, switch the simulation to the Game. In this mode, you can try to figure out which reactants cause the products you see based on a given chemical equation (or vice versa in Level 2). Following completion of the simulation, write a 260- to 350-word response answering the following: What did you do during the simulation? Briefly describe. What did you observe? What do your observations teach you about chemical reactions and the conservation of matter? What additional questions does this make you wonder about related to chemical reactions and the conservation of matter? In your response, include some of the new vocabulary introduced in this week’s reading, such as: Reaction Reactants Products Molecules Submit your assignment.

CHM 110 Wk 5 - News Report Interview Video If needed, watch “Today’s Tip: How to Film a Video of Yourself” to assist you with recording a video of yourself. A transcript for “Today’s Tip: How to Film a Video of Yourself” is also available. Imagine that you are a forensic scientist assigned to analyze the scene of a nearby restaurant that has recently been destroyed by a fire. The local news is requesting that you describe what happened to the general public in a short interview so the local community can have some questions answered.
Prepare a 3- to 4-minute video or a transcript of 700-1,050 words to submit for your interview. In your video, your goal is to educate the public about the chemistry involved in what happened and how chemistry will help provide additional answers. In the interview, ensure you: Describe what happened. Use your understanding of states of matter, energy, and chemical reactions to support your response. Describe the additional chemical evidence or other scientific factors related to chemistry that you will be investigating. Use your understanding of acids and bases and states of matter to share the types of information you will be gathering. Summarize how the general public can enhance their safety and prevent fires. Use your understanding of chemical reactions and energy to support your recommendations. Remember, your audience is the general public. As a scientific professional, you will need to use your expertise of scientific concepts to inform your audience while still using words that are accessible and easy for everyone to understand.
