Begin the lesson by introducing the concept of pulleys as simple machines. Discuss their everyday applications, such as on boats for lifting sails or cargo.

Engage students with a question: 'Have you ever seen a pulley in action?' Encourage them to share examples from their experiences.

Explain the basic components and functions of a pulley, emphasizing the difference between fixed and movable pulleys.

Use the video 'Simple Machines – Pulleys' to demonstrate how pulleys alter the direction of effort and reduce the force needed to lift loads.

Discuss the advantages of using pulley systems that combine multiple pulleys to reduce effort and change the direction of force.

Watch the video 'Simple Machines – Wheel and Axle' to understand how different simple machines work together to make tasks easier.

Conduct a hands-on activity where students use materials to create a simple pulley system and observe how it reduces the effort needed to lift a load.

Use the 'Investigating Pulleys' assessment to guide students in setting up pulley systems and recording observations on the force required.

Assign students to research and present on different types of pulleys and their applications in various industries.

Use the 'Simple Machines' assessment to evaluate students' understanding of how pulleys and other simple machines function.

Have students reflect on the lesson by discussing how pulleys make work easier in everyday tasks.

Conclude with the 'Review – Work and Simple Machines' assessment to reinforce the concepts learned.
