For Science Day we carried out an investigation. We had to find a way to make a toy float on top of the water. We tested lots of materials. Some of us made boat structures out of card, while others tested rubber bands, bags and sponges. We found that the best way was to put the toy in a bag and then make it air tight by tying the bag with rubber bands. We then created posters to try and sell the new inventions!
P.s: we managed to get quite wet in the process!
