Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials.
Energy is a key principle in physics. Forces cause changes and energy calculations allow us to measure how much change can happen.
Relative formula masses can be calculated and used in conservation of mass calculations. Calculations can be carried out to find out concentrations of solutions.
Scientific investigations have several stages - planning, collecting data, analysing data and evaluation. It is important to understand how to carry out each stage of the investigation.
Matter is made up of small particles called atoms. Atoms can exist on their own or together as molecules. Atoms are very small and around 100,000,000 of them side by side would measure 1 centimetre.
Magnetism and electromagnetism are due to the magnetic fields around magnets and around electric currents. The fields can be investigated by the forces they exert on magnets and magnetic materials.

Energy can be described as being in different 'stores'. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.
