    In the next few days I'm going to be completing my GCSE Biology ISA for AQA, the topic is photosynthesis, and Biology is my weakest science.

    Can someone help with a context idea for doing an experiment about light intensity affecting the rate of photosynthesis.

    I've done my GCSE Chemistry ISA and got 47/50, however our teacher for biology isn't helpful and would appreciate any help. Thankyou

    we do this experiment in a level bio but it should be similar right?
    Using a photosynthometer
    1) control temp, carbon dioxide conc etc.
    2) use a source of light at differing distances
    3) count the gas bubbles escaping from the subject
    4) take the reciprocal
