As part of our Science work on Everyday Materials, we did an investigation to see which material would be best to use for Tommy Turtle’s umbrella. We made a prediction and then decided how to test each material in a fair way. We decided to put 10 drops of water on each material and see if the water soaked through to the other side. We made careful observations and recorded our results in a table. We found out that plastic is the best material for the umbrella as the water did not soak through.
