Science
Science in Key Stage 3 deepens the three disciplines toward GCSE. Students study cells, body systems and ecosystems in biology; particles, atoms and reactions in chemistry; and energy, forces, waves and electricity in physics.
#️⃣ Topics in Science
Each topic has lessons, quizzes, games and printables.
Biology: Cells, Respiration & Photosynthesis
Life works at the cellular level. This topic covers cells, respiration and photosynthesis — the processes that power living things.
Explore →Biology: Human Body Systems & Genetics
The body is a system of systems. This topic covers human body systems and an introduction to genetics and inheritance.
Explore →Biology: Ecosystems & Health
Living things depend on each other. This topic covers ecosystems, food webs, and what keeps the body healthy.
Explore →Chemistry: Particulate Nature of Matter
Everything is made of particles. This topic covers the particle model, states of matter, and how it explains changes we…
Explore →Chemistry: Atoms, Elements & Periodic Table
Atoms are the building blocks. This topic covers atoms, elements and compounds, and how the periodic table organises them.
Explore →Chemistry: Chemical Reactions & Acids/Alkalis
Reactions rearrange matter. This topic covers chemical reactions, acids and alkalis, and neutralisation on the pH scale.
Explore →Chemistry: Earth & Atmosphere
Chemistry shapes our planet. This topic covers the Earth’s structure, the rock cycle, and the composition of the atmosphere.
Explore →Physics: Energy Stores & Transfers
Energy cannot be created or destroyed. This topic covers energy stores, transfers, and conservation in everyday situations.
Explore →Physics: Forces, Speed & Pressure
Forces govern motion. This topic covers forces, speed and motion, and pressure in solids, liquids and gases.
Explore →Physics: Waves, Sound & Light
Waves carry energy and information. This topic covers wave behaviour, sound, and light including reflection and refraction.
Explore →Physics: Electricity, Magnetism & Space
From circuits to the cosmos. This topic covers electricity and circuits, magnetism, and an introduction to space physics.
