We wanted to see how important water and light are when growing plants.
We tried to make our experiment fair by using 3 tubs the same size, using 8 balls of cotton wool in each tub and measuring a spoonfull of seeds to go into each one.
We put cress seeds into tubs with cotton wool and changed the conditions for each one.
Tub 1 was given water but no light (we put it in the cupboard!)
Tub 2 was given water and given light.
Tub 3 was given no water but was given light.
We guessed which tubs we thought cress would grow in and recorded our thoughts.
Here are the photos of our results, Do you know which ones are which?
