This week in DT year 3 have been testing the water resistance of different materials for their shelters project. We tested paper, fleece, sponge, card, cloth, cotton wool and lots of other materials.

After testing one material at a time we decided that in order for materials to be the most water resistant we would need to use a number of materials to support each other. The best we decided would be a bottom layer of sponge then cotton wool with cellophane across the top.

This video is from two weeks ago from the DT lesson where we tested the strength of different materials.

    You have worked very hard on your shelters and it seems that you have learned lots about materials, their properties and how to make the most out of different materials. Well done Year 3!
