Changing ideas about Earth

In the Gravity in space unit, they will build on this knowledge to learn to how gravitational forces cause orbital motion and about stellar evolution and cosmology, including red-shift and the big bang. 

In primary science, pupils learnt about the cause of day and night, the movement of Earth orbiting the Sun and the Moon orbiting Earth, and about stars and planets we can see in the night sky.

This unit explores gravity as the force between masses, including weight calculation using gravitational field strength. It covers the relationship between Earth, the Moon, and the Sun, the concept of light years, and seasonal changes due to Earth’s tilt.
