Biology ISA research help

Hey ah, I'm doing my ISA section 1 soon and It's on limiting factors of photosynthesis.
I am investigating the hypotheses that light intensity varies rate of photosynthesis and my main method is moving the lamp different distances and counting bubbles.

There's a Q on an alternative method you found and why you didn't use it but I cannot think of any other experiments following the same hypothesis... Any help??
Cheers.

My Biology teacher said we only needed to research one method, but just in case I thought of another method. How about changing the brightness of the light instead of the distance for your alternative method?

This year My ISA is on the effect of ph on amylase to hydrolyse starch, I have done the experiment, any help/ideas for possible questions for the exam paper? :smile:
