This week Year 1 have been continuing their work on materials in Science with some exciting waterproof experiments. We needed to find a suitable material to make an umbrella for teddy. We used tiny plastic teddies in a clear cup and placed different materials on the cup. We held them tight with an elastic band and then dropped water onto the material.
We had to be fair and put the same amount of water into our syringe each time. We then tested each material in turn, predicting if teddy would get wet before we started. We discovered that lots of materials kept teddy dry including paper, but that the paper began to soak up the liquid and would get wet eventually. We decided that plastic would be best for teddy as it had no holes, would be light to carry and would bend to close up.Previous
