Collaborative, Fun, Listening & Talking, Problem Solving, Science Young Scientists February 10, 2016 Mrs Toman Our predictions didn’t match the outcome! Our group couldn’t agree if cardboard was waterproof or not………. We tested different materials to see if they were waterproof. The plastic bag was waterproof. The paper towel wasn’t waterproof. We took turns to use the pipette. We tested 5 different materials. We worked in a group. The PVC fabric was waterproof. We had fun too!
