Physics: Space Physics 2


Pupils will learn about the formation of stars and study evidence to show that our universe is ever expanding. They will discover how objects remain in orbit, and how scientific theories are ever developing and evolving. Pupils should also review the keywords from the previous Year 8 Space Physics topic.

The main SMSC/Personal Development content of this topic include: PD13 – Ability to be reflective about their own beliefs (religious or otherwise) and perspective on life.
PD14 – Knowledge of, and respect for, different people’s faiths, feelings and values.

Centripetal Force

Force, needed for circular motion, which acts towards the centre of a circle.

Big Bang Theory

Cosmic Microwave Background Radiation
