Mrs. Stein started off the class by showing us an amazing demonstration of enzymes reacting to other substances. In this demonstration she had hydrogen peroxide, potassium iodine (our enzyme), and a huge cylinder. She poured only a little bit of the hydrogen peroxide in the cylinder and then she sped up the diffusion by adding potassium iodine and in a matter of one second, the hydrogen peroxide foamed like crazy and shot out of the cylinder. Of course, before this experiment, Mrs. Stein had put on her goggles and reminded everyone that they should be worn in the lab we we're about to do. This was a fun demonstration that got every ones attention the second the substance started foaming up. Now every single person was astonished and awake.

Then later on we started our Enzyme Lab and we were assigned to find out how the catalase reacted in our group’s different temperatures. In the lab we used hydrogen peroxide, sucrose solution, catalase, and water. We were to do three experiments in all, and in almost all of them, the substance started to bubble.

Then towards the end of class we were supposed to have experiments with the substances in our specific temperatures. We did as many experiments as we could until class was over.
