Classroom Ideas

Giving children torches and opaque toy models could help them to explore how shadows are formed. Challenging children to see if they can make more than one shadow by using two or three torches will allow them to deepen their understanding of how shadows are created. After watching this clip, pupils may be instructed to make their own shadow puppets or sundials to consolidate their understanding of how shadows are formed.
