The enzymes reaction in 7 different potato slices when put in various temperatures and hydrogen peroxide added to each Potato slice.
Hypothesis: I think that if the temperature of the potato is colder than it wont react as fast but if the potato is boiled then it wont have a reaction at all. I think the potato would show the best results and reactions if it were just left in its original form.

Purpose: This lab determined if temperature really affects an enzymes reaction rate.
Constants: Potato at room temperature.
Control: Type of potato, size of slice , and the same amount of hydrogen peroxide.
Materials: Dropper, hydrogen peroxide, Beaker water glass stirring stick // thermometer, ice weight boat, tongs, hot plate, oven mitt, knife, ruler, paper towels.
These are all the substances that I added . You can use what ever materials you need but this wil get you very good results.
Analysis Questions:
1. When hydrogen peroxide touches the enzymes in your body it is breaking down the hydrogen peroxide getting all of the bacteria and infections out that are not needed in your body.2. Just like the potato , the hydrogen peroxide is getting broken down by the enzyme peroxidase and it is getting rid of all the bacteria that is not needed.
