Begin with a discussion on what students already know about mixtures. Use examples like salad or trail mix to illustrate the concept of a mixture and how it differs from a pure substance.

Introduce the concept of heterogeneous mixtures, explaining that the components are not mixed evenly and can be easily separated. Use a salad as a visual example.

Discuss suspensions and how they differ from other heterogeneous mixtures. Use examples like oil and water to illustrate.

Watch the video 'How Can You Separate a Mixture of Sand and Stones' to learn about sifting as a separation method. This video provides a practical demonstration of separating components based on size.

Explore the video 'Separating Mixtures – Evaporation' to understand how evaporation can separate a saltwater solution. This video illustrates the process of evaporation and its applications.

Conduct an experiment to separate a mixture of sand and water using filtration. This hands-on activity helps students understand the practical application of filtration in separating mixtures.

Encourage students to find and classify mixtures at home or in the classroom. They should identify whether they are homogeneous or heterogeneous mixtures.

Use the 'Mixtures and Solutions – Comprehension' assessment to evaluate students' understanding of heterogeneous mixtures. This worksheet helps reinforce the differences between heterogeneous and homogeneous mixtures.

Reflect on the learning objectives and discuss how the activities helped achieve them. Encourage students to share their thoughts on the separation methods they found most interesting.

Administer the 'Review – Matter' assessment to test students' comprehension of the topic. This assessment includes tasks that require students to apply their knowledge of mixtures and separation techniques.
