A practical demonstration, using visual aids, to show how the Sun shines on the Earth and how the Earth rotates to create day and night. The demonstrator talks about the Sun rising in the east and setting in the west, and the effect on the length of shadows created at different times of the day.

After showing the clip, students could simulate the same investigations with globes, torches and building blocks. They could answer true or false questions about an explanation of why there is day and night, why the Sun rises in the east and sets in the west, and how shadows are formed. In the playground, students could draw around their shadows with chalk. They could then come back to the same spot at different times of the day and do the same thing. They will be able to track their shadow and its shape throughout the day.
