Why did Year 2 learn about nappies today?

This term we have been investigating materials and their suitability for different purposes. Today we talked about all the features a disposable nappy would need: waterproof exterior , soft comfortable and absorbent. We carried out tests on real nappies and also watched a clip about the tests in a real-life disposable nappy factory. After this we worked in teams to design and make the best nappy. We had a range of materials; plastic, cotton wool, sponges, towels, felt, tissue and paper towel. We also had some ‘ magic snow’ this powder absorbs water so behaves in a similar way to ‘sodium polyacrylate’ found in real nappies .

Look at our photos- what a super scientific  afternoon!
