ach table had 4 paper cups filled with water. Mrs Tubby then put a few drops of different food colouring in each group - red, blue, yellow and green.
We then had to scrunch up some kitchen roll to place between the cups. After a few minutes of observing what happened, we noticed that the kitchen towel was absorbing the water and the coloured water was being absorbed further and travelling up the towel.
Some of noticed that some of the colors seemed to be absorbed better than others - in particular the green and blue.
The children used some great scientific vocabulary to describe what was happening.
