Classify Matter
- Classify a substance based on its physical properties using the terms: homogeneous, heterogeneous, pure, mixture, solution and/or compound. Describe different properties of solids, liquids and gasses and classify these properties as extensive or intensive and as physical or chemical. Explain the difference between atoms, molecules and ions. (B1/B3)
Names and Formulas
- Write the names and formulae for ionic and covalent compounds given appropriate charts and data tables. (B2)
Physical and Chemical Changes
- Explain the difference between physical and chemical changes, giving examples. Relate changes in temperature to changes in molecular motions and arrangements during phase changes. (B4)
Physical Separation
- Choose appropriate methods of separation based on a mixture's components including filtration, hand separation, evaporation, chromatography and distillation. (B5)
