Key Stage 4 Science

KS4 Year 9


First half-term is a review of key fundamental areas of KS3 that need to be consolidated or finished.

Cells 1: Pupils will study microscopy, prokaryotic and eukaryotic cells, Specialised cells, diffusion, osmosis and active transport.

Atoms: Atoms, chemical equations, revisit separating mixtures and application, history of the atom, Ions, isotopes. 

Energy Conservation: energy changes in a system.


Cells 2: Pupils will look at mitosis, cell cycle, revisit specialised cells.

Periodic table:  Study the development of the periodic table, organisation, patterns and trends of groups 1, 2, 7, 0 and transition metals.

Energy and Heat: Revisit KS3 knowledge on conduction, convection and radiation and extend to application in the real world.

Organisation 1: Digestive systems and explore factors affecting enzymes that extends upon KS3.

Organisation 2: Circulatory system.

Structure and bonding: Study types of bonding such as covalent, large covalent molecules, ionic and metallic bonding.

Energy Resources: Explain ways to generate electricity and evaluate their use.


Electricity: Circuits and components.

Chemical changes: Chemical reactions.

Organisation 3: Plant tissues and organ systems.

Electricity & Home: National grid and wiring a plug.

Energy (Chemistry): Exothermic and endothermic reactions, energy profile diagrams.

Infectious diseases: Introduction to pathogens and how our body responds.
