Uh-oh! Ted has a hole in his coat and will get wet in the rain! I wonder would Room 7 be able to make him a new coat?
We tested a variety of different materials to see which ones are waterproof and which are not. We discovered that the water soaked through paper, tissue, cloth, cotton and sponge. But the water just ran off the plastic and tin foil – this means that they are waterproof!
Room 7 love experiments and developing our scientific skills like predicting, observing, testing, recording and evaluating. Look at some pictures of our experiment here.
