- I can describe the features of the moon’s surface.
- I can state at least one theory about the formation of the moon.
- I can explain why the phases of the moon, eclipses and tides occur and interpret diagrams of relative positions of the sun, moon, and Earth during these events.
25.3 The inner solar system
- I can compare the terrestrial planets and describe characteristics of each.
