Pondweed is a plant that photosynthesises in the light, releasing oxygen gas as a waste product.
Planning an investigation into the effect of light intensity on the rate of photosynthesis in pondweed.
Identifying the independent variable (light intensity) and planning how to vary it.
Identifying factors that should be controlled and how they could be controlled (e.g. temperature).
Planning methods to measure the dependent variable (number of bubbles and volume of gas given off).
