About this worksheet
A museum curator has dropped a box of display labels, and Year 3 pupils sort them on this three-page light worksheet. There are twelve objects, from the Sun and a glow-worm to a flat mirror and a diamond ring. Pupils write each one under Light Source or Not a Light Source. Two follow-up questions ask for the hardest item to place and for one new example of each kind. The answer key lists the full sort and explains the common traps, such as the Moon. It is one of the Year 3 light objectives in the England National Curriculum.
