Levers. Pulleys and Gears - Teacher Explanation is part of the lesson Levers. Pulleys and Gears    Students will learn about levers. pulleys and gears as part of their learning about forces, as specified by the national curriculum in England: science programmes of study.

Welcome to lesson 5.5 on Levers, Pulleys, and Gears, part of the Year 5 Forces unit in line with the National Curriculum. This lesson will help pupils understand how mechanisms like levers, pulleys, and gears can amplify a smaller force to achieve a greater effect. Safety is key, so any spills from liquids used in the lesson should be promptly cleaned up. Additionally, caution is advised when handling bamboo skewers due to their sharp ends. The lesson offers cross-curricular opportunities, such as Design and Technology, where pupils will create a simple lever, and Mathematics, where they can graph their experimental results. They can also delve into the historical significance of these mechanisms by researching ancient construction marvels like Stonehenge and the pyramids of Giza.

The class activity introduces the concepts of fulcrum, load, and effort through the practical example of a classroom door, demonstrating how a door functions as a simple lever. Pupils will experiment with the placement of force on the door, observing how the distance from the fulcrum (the hinges) affects the effort needed to move the door. This hands-on approach helps them understand the principles of levers. They will also explore pulleys by setting up a system that demonstrates how pulleys can reduce the effort needed to lift a load. Finally, the lesson on gears will have pupils construct their own gears, learning about gear ratios and how different sized gears affect the effort required to move an object. This comprehensive lesson aims to provide a fun and engaging way for pupils to grasp the practical applications of simple machines in our everyday lives.

In this lesson, students will learn about the basic concepts of levers, pulleys, and gears, and how they are used to make mechanical work easier. They will learn that by using these mechanisms, a smaller force can have a greater effect. The lesson will cover four main objectives: <ul> <li>State that machines can make mechanical work easier.</li> <li>Explain that the longer the lever, the less effort needed to lift a load.</li> <li>Explain that adding pulleys reduces the effort required to lift a load.</li> <li>Describe the effect of a larger cog on a smaller cog.</li> </ul> This lesson is suitable for students in year 3 who have already been introduced to forces and magnets. The lesson plan also has cross-curricular links with design and technology, mathematics, and history. Students will make a simple lever and graph their experimental results, and learn about the history of pulleys and their usage in ancient civilizations. The lesson plan includes activities that will help students understand the concepts of effort, load, energy, fulcrum, pivot, mechanical, pulley, gears, cog, and rotation. Influential scientists such as Archimedes, Hero of Alexandria, Franz Reuleux, and Simon Stevin will be introduced in the lesson. The teacher will need to purchase a gear set as it is not possible to make them in class. The class will participate in a demonstration to show the effort required to lift a load can be reduced by using pulleys. The lesson will also include an activity where students will learn how the classroom door functions as a lever and how the position of the fulcrum affects the effort required to move a load. In conclusion, this lesson is a comprehensive introduction to the basics of levers, pulleys, and gears and how they can be used to make mechanical work easier. Students will learn how simple machines work and be able to apply their understanding to real-world scenarios.
