Variables
Independent Variable
Our independent variable is the amount of hydrogen peroxide used
Dependent Variable
The dependent variable is the amount of time it takes for a noticeable reaction between the catalase and hydrogen peroxide to happen.
Consistent Variables
Our independent variable is the amount of hydrogen peroxide used
Dependent Variable
The dependent variable is the amount of time it takes for a noticeable reaction between the catalase and hydrogen peroxide to happen.
Consistent Variables
- We kept our method of timing throughout the experiment consistent, however there may have been some errors due to the fact that people aren't perfect and there is always the possibility that we could make a mistake when we stop/start the time.
- The size, thickness, and amount of skin on the potato was kept consistent.
- The exposure point on the potato was kept consistent because we always poured
the hydrogen peroxide onto the center of the potato rather than the side where
it may not have reacted as quickly due to the skin of the potato.
