Can you keep the sweets dry?Add to My Folder
Teachers’ notes: Pour some water onto a plastic bag with coloured sweets inside. Ask what would happen to the sweets if they were not in the plastic bag. Show the children a range of fabrics such as cotton, denim, net, card, greaseproof paper and kitchen foil. Ask them why some materials are waterproof and others are not. The children should choose three materials and guess if they think they are waterproof. Carry out the experiment and record the findings.
