We set up a fair test experiment to investigate this question.
We have left three green plants ( the same kind) in the same place, (with the same temperature, amount of light and size of pot) for a week.
The only condition we have changed is the amount of water we give to the plant each day.
Plant A has 200 ml of water.
Plant B has 100 ml of water.
Plant C has no water.
We have made predictions and will look at our results next lesson!
