Catalase Temperature Lab

In this lab, I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃, then it will break down the peroxide faster because yeast tends to rise faster as the temperature increases. Some constants in this lab are: the 10 mL of peroxide, the 190 mL of water, the same timer, the same sheet of filter paper and the
When the water was at 10℃ the average rate of reaction was 1.75 mm/s. When the water was at 25℃ the average rate of reaction was 2.98 mm/s. When the water as at 37℃ the average rate of reaction was 3.45 mm/s. Finally, when the water was at 45℃ the average rate of reaction was 4.07 mm/s. Therefore, our data did support our hypothesis because we hypothesized that when the water rose in temperature the reaction rate would speed up, and so it
The following is a description of all the variables that were controlled: the room temperature water at 25℃. This left us with with only one variable in this experiment which was the different temperatures we were testing.
If i was to design this investigation again, I would use more temperatures than just 4 to give a wider range to experiment with. Also, i would have used more than one catalase because it gives you a chance to see which catalase can work the best under each temperature. Finally, I would instead of using water and heating it up, I would use a different substance for example alcohol or juice. To verify our data, I would repeat the experiment 20
