We have been learning about different materials, their uses and their properties. We know that a shelter can have different materials depending of if it is for an animal, including a human, a plant or an object. What is needed in a shelter for a hedgehog is very different to what’s needed for a human! We wanted to look specifically at the property of being waterproof. We tested different materials to see how waterproof they would be. We knew, if they let water through them, then it is not waterproof. We made a prediction, set up our experiment and recorded our results.
