The children in year are really impressing us with the scientific skills they are developing this year. About light, they can say what a light source is, name a number of different light sources and address common misconceptions about light sources. For instance, they can explain that a mirror is not a light source but is merely a good reflector of light. They loved applying their knowledge of reflection to designing a school back pack, with all of them remembering to include retroreflective material within their design.
