For this week’s science lesson, we conducted an experiment. We wanted to find out if changing the colour of water would make our carnations change colour, as the water moves through the stem.
We predicted what might happen first. Lots of children thought that the carnation would change to match the colour of the food colouring that was used.
In order to ensure this was a fair test, we used the same amount of water and food colouring. We will keep the carnations in the same conditions and will observe them over the same length of time.
