Year 8 Science
Cells and the organ systems they build, what a plant does with light and what an animal does with food, who eats whom in a habitat — and on the other side, particles, elements, compounds and solutions, forces that touch and forces that do not, and what a current does to a magnet.

- The cell, the basic unit of lifeLesson
Name the parts of a cell and what each does, tell a plant cell from an animal cell, and put the levels of organisation in order.
- Life processes in animalsLesson
Follow food through the alimentary canal and say what each part does, tell breathing from respiration, and match an animal to the way it takes in oxygen.
- Life processes in plantsLesson
Say what photosynthesis needs and what it gives back, read the experiment that proves each ingredient, and name the tubes that carry water up and food out.
- Microorganisms around usLesson
Name the main groups of microorganisms and say what they do for soil, food and crops.
- Ecosystems and food chainsLesson
Separate the living and non-living parts of a habitat, build a food chain, and name the three ways two organisms can live together.
Chemical sciences
- The particulate nature of matterLesson
Explain the three states of matter by how tightly their particles are held and how much space sits between them.
- Elements, compounds and mixturesLesson
Tell an element from a compound from a mixture, and say which of them can be taken apart by physical means.
- Solutes, solvents and solutionsLesson
Name the solute and the solvent in a solution, tell a saturated solution from an unsaturated one, and say how temperature changes what will dissolve.
- Density, and how to measure itLesson
Calculate density from mass and volume, find the volume of an irregular solid by displacement, and say what heating does to density.
Physical sciences
- Forces: contact and non-contactLesson
Sort forces by whether they need the objects to touch, read a spring balance, and keep weight and mass apart.
- Magnetic and heating effects of currentLesson
Explain how a current makes a magnet and how it makes heat, and say what changes the strength of an electromagnet.
- Mirrors and lensesLesson
Tell concave from convex for both mirrors and lenses, use the laws of reflection to find an angle, and say which of them gathers a beam and which spreads it.
