Year 1 – Is it waterproof? How much water does it absorb?

We used simple apparatus to test whether a material was waterproof and if not how much water it absorbed. We made a prediction and then tested and observed closely the materials to see what happened. We talked about how to make it a fair test and had lots of discussion on why certain materials might respond in different ways.
