Who are we? Our Mission!
REMEMBER TO CHECK OUT OUR FACEBOOK PAGE and LIKE it! https://www.facebook.com/ juniorscienceclub?ref=br_tf!
The Junior Science Club was established for Form 1-2 students of the school," who may not possess adequate knowledge for the activities held by other science clubs. It aims to promote the pursuit of scientific knowledge among junior form students and spark their interest in science. " Through organizing simple but intriguing experiments, activities and outings, the Club hopes to act as an introduction for lower form students to the further exploration of the endless possibilities in science. "
What’s on our Facebook page? Updated information on our up-coming activities and pictures from past events that you may be included in. And what’s more? Video, Book Recommendation or Science Websites will be uploaded in our Facebook page from time to time. Science is literally just a click away:)
The Junior Science Club also aspires to serve the school’s student profile, in particular the passionate-learning and critical-thinking attributes of students, by sharing peripheral knowledge alongside the school science curriculum, and thus nurturing and enhancing the intellectual development among junior form students.

Bits of Science . . . BIOLOGY ‌ Heart and Circulatory System The heart is one of the most crucial organs in the human body. It pumps to propel blood throughout the body, carrying oxygen and nutrients to every cell. Every day, the approximately 5 litres of blood in your body travel many times through about 96,560 kilometres of blood vessels that branch and cross, linking the cells of our organs and body parts. Unlike what the stories usually tell us, the heart is not able to understand our deepest feelings. It plays a main role in maintaining our lives. The circulatory system consists of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: pulmonary circulation and systemic circulation. The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation sends blood from the heart to all the other parts of our bodies and back again. The heart has four chambers that are enclosed by thick, muscular walls. The bottom part of the heart is divided into two chambers called the right and left ventricles, which pump blood out of the heart. The two ventricles are divided by a wall called the interventricular septum. The upper part of the heart is composed of the other two chambers, the right and left atria (singular: atrium), which receive the blood entering the heart. A wall called the interatrial septum divides the right and left atria. There are two valves separating the left atrium and ventricle, and the right atrium and ventricle. There are two types of blood vessels in the system: arteries and veins. Arteries, which have muscular walls that contract to keep the blood moving away from the heart and through the body, carry blood away from the heart. There are two main arteries, namely the aorta, which extends from the left ventricle to the other part of the body, and the pulmonary artery, which links the right ventricle to the lungs. Veins are used to carry the blood back to the heart. There are also two main veins, including the vena cava and the pulmonary vein. The former carries the oxygen-depleted blood from the body back to the heart, while the latter carries the oxygenated blood from the lungs to the heart. After the blood circulates in the body, the oxygen-depleted blood enters the heart through the left atrium to the left ventricle. Then it flows out through the pulmonary artery to the lungs to gain oxygen and get rid of carbon dioxide. From the lungs, the oxygenated blood returns to the left atrium. It then enters the left ventricle and is soon pumped to the other parts of the body through the aorta. When the oxygen-depleted blood returns to the heart, it enters the left ventricle and then flows to the lungs again. This circulation goes on and on. It is how our circulatory system works.

CHEMISTRY‌Why do onions make you cry?
!
If you have ever chopped an onion in your life, you must have experienced the awful situation of tears running down your cheeks during the slicing process. Forget doing it for real, the mere thought of chopping onions makes me cry. So, what’s the reason behind the same? Why do onions make you cry? This is a little explanation in easy terms. Inside the onion cells there are some chemical compounds that contain sulfur. When you cut an onion its cells are broken and those chemical compounds then undergo a reaction that transforms them into a more volatile sulfured products, which are released into the air. The air starts moving towards your eyes. These sulfured compounds react with the moisture in your eyes forming sulfuric acid, which produces a burning sensation and starts irritating the nerve endings in the eyes. The nerve endings in your eyes are very sensitive and so they pick up on this irritation. The brain reacts by telling your tear ducts to produce more water, to dilute the irritating acid. So you cry to keep your eyes protected from the acid. Here are some tricks to make onion-slicing less problematic: - Chop the onion under cold water. The volatile sulfured compounds will be released but then they react with the water, instead of reaching your eyes. - You can freeze the onion for 10 minutes before cutting it. The cold temperature of the onion will slow down the chemical reaction which forms the volatile sulfured compounds. -You can light a candle while cutting onions. The gas releases while chopping onions move towards the candle flame instead of your eyes. -You can also avoid slicing the onion till the root, as this part carries the maximum concentration of sulfides. ! !

INTRODUCING‌ Just a Guy that Somehow Happened to be Sitting Under an Apple Tree‌Isaac Newton!
!
What do you think of when you hear the name Isaac Newton? An apple falling on a head? Some boring facts? Newton's laws? Or a crazy scientist with those messy hair."
!
In fact, Isaac Newton is so much more than these things. Ne w t o n w a s a n a v e r a g e b o y w h o g r e w u p w i t h h i s grandmother. Although he had a profound interest in science, he was never the smartest kid. He graduated from Cambridge without any honours or distinctions at all. Despite all this, he eventually became one of the most famous scientists who set the vary basis of lots of things in modern physics."
!
Newton didn't discover anything new. In fact, you might have made observations which are related to Newton's laws without realising it, such as when a car stops suddenly, you will continue moving forward until you hit something or your seatbelt stops you. This is related to newton's first law." Lots of discoveries are made when people pay attention to the small details in everyday life. As Marilyn vos Savant once said, "To acquire knowledge, one must study; but to acquire wisdom, one must observe." We should all be inquirers and ask more questions about observations in our daily lives."

PASt eventS Pig heart dissection workshop!
!
The first biology experiment was held on Wednesday and Thursday and the workshop is about the dissection of the pig heart.
!
The participants were divided into several small groups of around 4 to 6 people. Each group had a pig heart and diagrams showing the different parts of the pig heart. Students from higher forms dissected the pig hearts whilst explaining flow blood flow with the help of diagrams. The heart was cut open the chambers inside the heart were revealed and the flow of blood was explained. Students had a rare opportunity to get a look inside the pig heart which is quite similar to that of the human heart.
!
Most students agreed that the most interesting part is getting to touch the heart and cutting it open themselves.
!
For students who missed this experiment, don't worry as there will be a chemistry workshop which will be held in November.
