A telescope is able to magnify distant objects so they can be seen in more detail.

Science

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 the Earth orbiting the Sun and the Moon orbiting the Earth, and about stars and planets we can see in the night sky.

Our solar system and beyond

It magnifies distant objects so that we can see them in more detail.

It helps light from our eyes reach the object we are looking at.

It shines light on the object we are looking at so we can see it more clearly.

Earth’s shadow on the Moon (during a lunar eclipse) is circular.
