In this chapter, we will be learning about machines.
We will start by understanding how levers work.
We will learn to identify the load, fulcrum, and force on the lever by doing activities.
We will also make generalizations about the relationship between the distance of the load from the fulcrum and the force required.
Next, we will learn about simple machines and complex machines.
We will explain the types and uses of simple machines using examples and by doing activities.
We will also learn how to solve problems using two or more simple machines.
By the end of this chapter, we will have a good understanding of how machines work and how they make our lives easier.
• Identify the load, fulcrum and force on the lever by carrying out activities
• Make generalisation on the relationship between the distance of load from fulcrum with the required force
• Explain the observations about the lever through written or verbal forms, sketches or ICT in a creative way
• Explain with examples the types and uses of simple machines by carrying out activities
• Solve problems using two or more simple machines
• Summarise the meaning of complex machines
• Explain the observations of the simple and complex machines through written or verbal forms, sketches or ICT in a creative way
