Exemplars (from the NaCCA curriculum)

- Display different types of liquids for learners to observe, e. g. water, kerosene, cooking oil, milk, soft drinks, etc.
- Task learners to identify the liquids provided.
- In groups, learners mix liquids of the same kind, different kinds and then observe and record their findings, e.g., vinegar and water, palm oil and water, etc.
- Engage learners in discussion to describe the different types of liquid-liquid mixtures. [Those which are able to mix uniformly (miscible liquids) and those which are not able to mix uniformly (immiscible)].
Project: Separation of a mixture of immiscible liquids. Learners investigate to separate a mixture of immiscible liquids such as cooking oil and water.
NB: This activity can be undertaken with the aid of a separating funnel or an improvised version of it. Do not bring liquids that are flammable or poisonous to class for this lesson.
