First, what is your test for the presence of starch? Iodine?

Once you have a test, then start with a standard solution (you decide) of starch, and a standard solution of amylase.

Put your standard solution of starch in test vials. Add the indicator solution.

Now, figure a way to monitor temperature of the vial.

Put your vial in a controlled temp (refrigerator, oven) and raise temp (or lower) by 5C. Then add amalyse, and measure reaction time. Do this for several temps.

Plot reaction time vs temp
