Begin the lesson by discussing a simple classroom experiment: sliding a book across different surfaces. This will introduce students to the concept of friction as a force that resists motion.

Engage students with questions about everyday experiences with friction, such as walking on different surfaces or using bicycle brakes.

Explain the concept of friction and its role in resisting motion between two surfaces. Use examples such as sliding on a rough carpet versus a smooth floor.

Discuss scenarios where high friction is beneficial, such as walking or using bicycle brakes, and where low friction is advantageous, like sliding down a slide.

Watch videos that illustrate the effects of friction in various situations. These videos will help students visualize how different surfaces affect friction.

Encourage students to think of examples in their environment where friction plays a role and discuss these in small groups.

Conduct an experiment to explore how different surfaces affect friction. Use a ramp and a toy car to test surfaces like wood, paper towel, and bath towel.

Assign students to find and document examples of friction in their daily lives. They should note whether high or low friction is beneficial in each case.

Use the 'Is Friction Helpful or a Hindrance?' assessment to evaluate students' understanding of friction's role in various scenarios.

Facilitate a class discussion to review the key concepts of friction. Encourage students to share their findings from the independent practice.

Administer the 'How Does Friction Affect Motion?' assessment to gauge students' understanding of how different surfaces impact friction.

For extension, students can explore the concept of friction in sports and how it affects performance. They can present their findings to the class.
