As part of our new topic 'Fabrics and Fibres,' Room 27 have been testing different materials to find out which one would be the best to use for making a raincoat for our class alien Zook. We decided that the fabric needed to be waterproof and that it also needed to be comfortable to wear.
We brainstormed ideas on how we could test the fabric to find out if it was waterproof, and decided that we would use spoons to drop water on each fabric to see whether the water came through the other side. Room 27 worked in groups of three to carry out the experiments. We tested six materials - cotton, hessian, plastic bags, tarpaulin, umbrella fabric and wool. We found that the tarpaulin, plastic bags and umbrella fabric were all waterproof. In our groups we then had to discuss which one of those would be the best for a raincoat.
Here is a black graph of our conclusion! 17 children thought that Zook would prefer the umbrella fabric as it was waterproof, light and comfortable to wear. 6 children thought the tarpaulin was better as it was waterproof and strong.
