Pupils investigate the formation of shadows and how the shape and size of a shadow can change according to the position of the light source, object and surface producing the shadow.
PoS - use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them, and to predict the size of shadows when the position of the light source changes
NaG - pupils should explore the way that light behaves
WS – pupils should take measurements, using a range of scientific equipment, with increasing accuracy and precision; report and present findings from enquiries, including conclusions, causal relationships and explanations of results, in oral and written forms such as displays and other presentations
