In this activity students will explore the differences between day and night on the Earth by comparing nocturnal and diurnal animals. They will investigate how day and night occur on the Earth using a simple model, and see how people and animals living in different parts of the planet experience different times of the day.
Long ago, when the world began, before the humans came, there was one Earth and there was one Sun, but there was no Moon in the sky. And at night – it was very, very, very dark! All the night-time animals found it very difficult to see. They bumped into trees, they fell over rocks, and, worst of all, they could not see to find their food.
