Pupils look at a range of materials and predict which ones they think are permeable or impermeable? Pupils record their predictions before designing an investigation to test their predictions.
PoS - compare and group together everyday materials on the basis of their properties, including their hardness, solubility, transparency, conductivity (electrical and thermal), and response to magnets
NaG - pupils should build a more systematic understanding of materials by exploring and comparing the properties of a broad range of materials
WS - pupils might work scientifically by: carrying out tests to answer questions, for example, ‘Which materials would be the most effective for making a warm jacket, for wrapping ice cream to stop it melting, or for making blackout curtains?’
