3rd class were investigating materials to see which would prevent damp rising - they tested kitchen paper, greaseproof paper, card and plastic. Before they carried out the test, they predicted that from worst to best the order would be: Kitchen paper, greaseproof paper, card, plastic. To keep the test fair, they tested the same size of material, used the same amount of liquid and the same number of sugar cubes. The card and greaseproof paper were surprisingly good at keeping the damp out but the plastic proved to be the best. Here are some photos of the experiments in progress:
