One year on Earth - Understanding seasons

In this activity you will learn about seasons by looking to the changing colours on Earth over the course of a year. First, by looking at photographs taken on Earth and then by analysing the colours in satellite images. You will also build an Earth-Sun model to explore why the Earth has seasons.
Explore with Paxi why we have day and night, and why the Earth has seasons.
