Everyday Materials 2

Today we have been investigating paper to find out if it is waterproof. We didn't think it would be because we have already found out that paper is absorbent.
However we discovered that baking paper is waterproof.
Then we wondered if it is possible to make paper waterproof.  Mrs Fortescue said that we came up with some very good ideas - which we then tested out.
Some of us laminated our paper, others added a waterproof covering to our paper and some of us coloured over the surface of our paper with wax crayons. We were amazed to find out that this worked.
