In our Materials topic we have been investigating whether materials are waterproof or not. We tested kitchen roll, tinfoil, fabric, plastic bags and tissue to see if they let water go through them. After testing all the materials we concluded that plastic bags and tinfoil are both waterproof. We also found out that kitchen roll is the most absorbent. We chose plastic as the most suitable material for making a raincoat. Well done Year One Super Scientists.
