Units
All 5 units of Science 7. Each one has a concepts page to learn from, practice questions marked as you go, and quizzes built at random.
Unit 1
Unit A: Interactions and ecosystems
How living things depend on each other and on the non-living world: who eats whom, where the energy goes, how matter is used over and over, and how an ecosystem changes after a fire, a new species or a new mine.
Unit 2
Unit B: Plants for food and fibre
What people get from plants, from food and cloth to medicine and shelter, how roots, stems, leaves and flowers keep a plant alive, what soil gives it, and the trade-offs in growing more food.
Unit 3
Unit C: Heat and temperature
The difference between heat and temperature, what particles do when things warm up, melt and boil, the three ways heat travels, and how we heat our homes and choose our energy.
Unit 4
Unit D: Structures and forces
What holds things up and what brings them down: the kinds of structures, the forces that squeeze, stretch, cut and twist them, and how triangles, arches and a low centre of gravity make a design strong and stable.
