From the lab ¨What happens in my body when I run around school?” I learned that exercising causes chemical reactions inside the human body. In the human body you have food molecules and you have oxygen. How do you think you get carbon dioxide. Your food molecules react with the oxygen which is a chemical reaction. When you run around the school, you can have multiple chemical reactions. This lab we did, was to see what happens to the body when we run around the school and when we exercise. Our body acts differently and we are different when exercising. The body sweats more and you breathe harder and your heartbeat is faster than usual. We wanted to see what happens so that’s why we did this lab and had people to go run up and down the stairs
