Science Lab 8

In the Science unit on Chemical Reactivity and Solutions, our Grade 8 students performed an experiment to study the activity of an enzyme called catalase found in the cells of many living tissues; such as the liver and potatoes (including humans). Students discovered the importance of how catalase speeds up a chemical reaction in which it breaks down hydrogen peroxide, a toxic substance that our cells produce as a byproduct of respiration, into two harmless substances; water and oxygen.
