The The 5 Chaps' have been studying atoms and molecules in Chemistry this week. We have discovered that atoms and molecules make up everything in the world. Scientists call these things materials which can be in the form of solids, liquids, or gases.
Today, we made a chemical reaction of a liquid and solid and created a gas called carbon dioxide by mixing vinegar and baking soda in a bottle. First, we poured about 1 cm of vinegar into a bottle. Then we poured 1 teaspoon of baking soda into a balloon.
Finally we put the balloon on the top of the bottle and shook the baking soda inside. The balloon began to blow up. Afterwards, we experimented with different quantities of our materials, like 1 inch of vinegar and 3 teaspoons of baking soda. When we increased the ingredients, we created more carbon dioxide.
Carbon dioxide is a gas. When we created carbon dioxide in the bottle, the balloon captured the gas. Normally, a gas's molecules spread out and bounce about so fast and escape without anyone seeing. Today, we were able to see the gas try to escape.
