Equipment

Variables

Change

The temperature of the reactants:

60

50

40

30

Control

Amount of peroxidase (10ml)

Amount of hydrogen peroxide (20ml)

Length of experiment (2min)

Time between measurements (15sec)

Equipment used

Safety

I will keep my safety goggles on at all times to prevent painful eye injury.

Method

For accuracy I am using six different temperatures and I will repeat the whole experiment twice.

I will
