Biology: Feeling hot hot hot!

This week we talked about homeostasis, the idea that our bodies need to keep things inside more or less the same despite an-ever changing outside environment. Our cells need a certain amount of oxygen, water, and energy in order to function. Furthermore, they can only carry out their metabolic processes within a particular range of temperatures. When we are in situations that challenge the status quo,the body must do something to compensate.

This week the kids designed and ran experiments to determine the effects of exercise on body temperature. Next week they will analyze their data and present their findings.
