Which material can we use to stop Freddy Teddy getting wet in the rain?

Today we looked at some different materials and thought about which ones would be good to make a raincoat for Freddy Teddy!

We felt the materials and chose ones that we thought would be waterproof.  We used a watering can to pour water like rain onto the materials and we looked into the pots underneath to see which ones had let water through - these were not waterproof! We found one that did not let any water through, this was waterproof. We were fabulous scientists!!!
