We made our boats... although not everything was found in the recycling bin!!
Which of the two boats do you think will float best? Do you think either will sink? What sort of materials float in water? Could you test some different materials in your bath?
Below are the videos to show you how we got on when we tested our boats on water. Were your predictions correct?
We'd love to see what you've all been up to.
Mrs Dennis and Miss Rowe.
