A collection of short explainer films by Professor Brian Cox comprising six clips focused on space physics.

In each of these clips both abstract ideas and those involving orders of magnitude difficult to imagine are explained simply and clearly.

Space physics is a topic that generally interests and excites students. Some of these clips go beyond what is required for the curriculum but will act to inspire and promote further curiosity in students.

These clips will help students to develop understanding and curiosity of space physics at KS3, or to reinforce and revisit at KS4.

They could also support non-specialist teachers in developing their own knowledge and understanding.
