to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved

2 major lab accidents: 1) Adam and Joey‚ best friends since kindergarten‚ were doing an experiment in engineering class. The boys launched a potato at the wrong rate of speed and distance and broke a school window when they were trying out their potato launcher that was made to be launched indoors inside the school lab. If Adam and Joey had listened carefully to the teachers instructions‚ they would have launched the potato to travel the correct distance and speed. Maria and Kathy‚ two girls who
