Additional Ideas 1. Chemistry fits into the science family because it helps us understand what everything around us is made of and because everything is made from chemicals. Without chemistry we wouldn’t know why things happen or what things that we use everyday are made from.

Chemistry is the study of matter and energy, and is used in our everyday lives, even if we are unaware of how.
