Waterproof materials

​During our science lesson this week the children were posed the question:
Which materials are suitable for making a waterproof coat?
They were then given a range of materials to handle and look at.  They were asked to predict whether they would be suitable for a waterproof coat or not.  They then tested the materials using water and a pipette to see if the material was waterproof and recorded the results in a table.  As a class we then discussed our findings and the children chose which material they thought would be most suited to make a waterproof coat and explained why.
