Classroom Ideas

When studying light and shadows, pupils can go outside on sunny days and draw around each others shadows to show how the Sun gives us light and when we block it, we have darkness. Introducing the difference between day and night can be modelled by asking the children to face a torch to represent day, and face away from the torch to represent night. Using a Lego man on a globe can also help to show how we have day and night.
