Question 1

Experiment

Answer 1

A source of light is placed at a specific distance from the pondweed

It is then left to photosynthesis for a set amount of time, it will release oxygen in a set amount of time (1min)

Count how many bubbles are seen coming off the pondweed, then repeat twice with the same distance.

Calculate the mean, experiment is repeated at different distances
