Begin the lesson with a discussion on how we can change matter in different ways. Introduce the concept of reversible changes using modeling clay as an example.

Show a short demonstration of melting and freezing using ice cubes to visually introduce reversible changes.

Explain the processes of melting and freezing as examples of reversible changes in matter. Use relatable examples like ice melting into water and refreezing.

Introduce the video 'Reversible and Irreversible Changes to Matter' to reinforce understanding of reversible changes.

Engage students in a discussion about other examples of reversible changes they observe in everyday life.

Watch the video 'Chemical and Physical Changes – Quiz Edition' to explore the differences between physical and chemical changes.

Have students use modeling clay to create different shapes and then return the clay to its original form to demonstrate reversible changes.

Conduct a simple experiment with ice and water to observe melting and freezing processes.

Assign the worksheet 'Reversible and Irreversible Changes' for students to identify and draw examples of both types of changes.

Review key concepts by asking students to explain reversible changes using examples from the lesson.

Use the video 'Changing Matter – Physical and Chemical Changes' to reinforce learning and clarify any misconceptions.

Encourage students to reflect on what they learned about reversible changes and how they can observe these changes in their environment.

Administer the 'Review – Matter' assessment to evaluate students' understanding of the topic.

Encourage students to explore further by trying the quiz at the end of the unit.
