AQA Chemistry Separating Mixtures

A trio of lessons to teach AQA Combined Science Chemistry (Section 5.1.1.2 – Separating Mixtures)

This three-lesson sequence covers the key methods of separating mixtures, aligned with AQA Combined Science.

Lesson 1 is theory-focused. It begins with a retrieval starter, followed by a series of teacher-led slides introducing mixtures and separation techniques, supported by quick-check questions and short activities throughout. A multiple-choice quiz reinforces understanding. The lesson concludes with an introduction to distillation, fractional distillation, and separating iron, salt, and sand.

Lessons 2 and 3 focus on practical work. In Lesson 2, students separate salt from rock salt using filtration and crystallisation. In Lesson 3, students carry out a distillation practical. Both lessons begin with a retrieval starter and include concise explanations of the methods used. As the distillation practical is shorter, Lesson 3 also includes additional AFL (Assessment for Learning) activities and an exam-style question to consolidate understanding.

All resources include full answer sets.
