Aim
To investigate the volume of oxygen given off when you react potato chips with different concentrations of hydrogen peroxide.

Variables
Surface area
Temperature
pH
Concentration

My chosen variable is concentration.

Fair test
I am going to make it a fair test by keeping the surface area of the potato chips the same. Different surface areas will not give you accurate results. Hav...
