science experiment

Today in Ruma Piwakawaka we did a science experiment! We put M&M's on a plate in a circle and put water in the middle and it made a rainbow. We also did a flower experiment. We put a flower in a glass of water and put food colouring in the water and the flower stem sucked up the colour and turned the petals a different colour. Have you ever done these two experiments? If you haven't have a go.
