Basically you will need mung beans at various stages of growth and hydrogen peroxide (amongst other things).

Hydrogen peroxide is decomposed by catalase (an enzyme) into water and oxygen at a rate which is dependent on the activity of the enzyme.

You can measure the rate of decomposition by measuring the volume of oxygen gas produced in a certain time period.

I'm not going to do your coursework for ya, but will help on specific questions, and advise on how to cover the criteria - if you need more advice, let me know.
