For Science Week, Fifth Class in Room 2 explored density with a rainbow experiment. We used honey, vegetable oil, Fairy Liquid, water and food colouring to make colourful layers in a jar and see how liquids of different densities stack up. We also took on a STEM challenge to build a bridge across a 21-centimetre gap between two tables using only 15 lollipop sticks. Then we tested our bridges to see which one could hold the most weight!
