Today we carried out an experiment to find out which materials are waterproof. We made boats using paper, foil and plastic and tested them out in the water tray. Sadly our paper boats fell apart and sunk. Some of the foil boats floated but some sank. We decided that foil is waterproof but that some sank because of the way they were constructed. The plastic boats were a great success and we blew on their sails to make them move. Super observations and discussions P2!!
