Begin the lesson by introducing the concept of mixtures and how they can be separated based on their properties. Discuss the importance of understanding these processes in everyday life and industries.

Explain the process of sifting and how it can be used to separate mixtures of solids with different particle sizes. Use a sieve to demonstrate the separation of sand and stones.

Describe the use of magnets to separate magnetic and non-magnetic solids in a mixture. Demonstrate with a magnet and a mixture of sand and iron filings.

Explore the concept of decanting by demonstrating how it separates mixtures based on density differences. Use a sand and water mixture to show the process.

Discuss practical applications of these separation techniques in industries such as recycling and water treatment.

Have students practice sifting by separating a mixture of sand and gravel using a sieve. Encourage them to observe and record their findings.

Conduct a magnetic separation activity where students use magnets to separate iron filings from sand. Discuss their observations and conclusions.

Assign students to explore the separation of mixtures at home using common household items. Encourage them to document their process and results.

Use the 'Mass and Volume' assessment to evaluate students' understanding of the properties of solids and liquids. This activity helps reinforce the concept of separation based on physical properties.

Facilitate a class discussion to review the different separation techniques learned. Encourage students to reflect on which method was most effective for each type of mixture.

Administer the 'Mixtures and Solutions – Comprehension' assessment to test students' understanding of heterogeneous and homogeneous mixtures.

Encourage students to explore further by researching real-world applications of separation techniques in industries like recycling and water treatment.
