This unit builds on unit 8E 'Atoms and elements'.
Work on temperature, melting points and boiling points relates to unit 8I 'Heating and cooling'.
This unit relates closely to unit 7G 'Particle model of solids, liquids and gases' and to unit 7H 'Solutions'. However, if teachers wish to introduce the idea of particles through unit 8E 'Atoms and elements', this unit could be taught before unit 7G 'Particle model of solids, liquids and gases' and unit 7H 'Solutions'.
Ideas in this unit about mixtures are picked up in unit 8G 'Rocks and weathering' and unit 8H 'The rock cycle'.
Consideration of air as a mixture relates to unit 8B 'Respiration' and unit 9B 'Fit and healthy'.
This unit, together with unit 8E 'Atoms and elements', provides the foundation for unit 9E 'Reactions of metals and metal compounds', unit 9F 'Patterns of reactivity', unit 9G 'Environmental chemistry' and unit 9H 'Using chemistry'.
