Chemistry: Science

Year 7 Chemistry follows AC9S7U05 (particle theory) and AC9S7U06 (pure substances and mixtures): one tutorial per hinge idea, plus filtration, evaporation, distillation and chromatography. Year 8 Chemistry upgrades the particles to atoms (AC9S8U06) and defines chemical change (AC9S8U07). Years 9 and 10 Chemistry open up the atom (AC9S9U06), follow the atoms through reactions and balanced equations (AC9S9U07), explain the periodic table with electron shells (AC9S10U06) and reaction rates with collision theory (AC9S10U07). Nodes whose response is a class task (such as choosing a separation technique, or conservation of mass in open and closed systems) are left to class work.

Foundations

Year 7 ChemistryParticles, mixtures and how to separate them.The particle model of matter, then pure substances, mixtures and separating them. Concept tutorials for introducing or revising each idea, with particle simulations.Year 8 ChemistryAtoms, compounds and new substances.The particle model gets an upgrade. Particles are atoms of different types, atoms join into compounds, and a chemical change makes new substances. Concept tutorials with atom-level simulations.After: Year 7 Chemistry

Extensions

Years 9 and 10 ChemistryInside the atom, balancing equations and reaction rates.Inside the atom and through reactions. The nuclear atom and its electron shells explain the periodic table; atoms rearrange and are never lost, which is why mass is conserved and equations balance; and reactions happen when particles collide hard enough.After: Year 8 Chemistry
