1) In a darkened room, shine the torch onto the globe. Which side is in the light? Which side is in darkness? Why?

2) Spin the globe very slowly anticlockwise (when looking down from the North Pole). How fast does the real Earth turn? How do we know this? Where is it light now? Where is it night?

Find Britain - stick the small figure onto the British Isles. Imagine you are that small figure. Is it day or night? Which direction would the Sun be?

Turn the globe a little - now what time is it for our little person? Is the Sun high or low in the sky? Do you think it is about to get dark?

Extra work:

Pupils who find this concept easy may like to use two or three figures in different parts of the world. Turn the globe very slowly, who goes to bed first? Who has the shortest day?
