Waterproofing experiment

As part of our science learning, P3/4/5 have been exploring the properties of different materials and why their different properties make them suitable for different jobs. This week we explored waterproofing and carried out an experiment to find out which materials would protect an item from getting wet. Before the experiment pupils discussed each material and its properties and made predictions about which material would be best for waterproofing. Next, everyone coloured in 6 dinosaurs and then covered these with the six different materials. The same amount of water was then applied to each. It was interesting to see which dinosaurs ink ran the fastest based on which material was protecting it.
