Hello, young learners! Welcome back to Primary 1 Basic Science & Technology. In our previous lesson, we learned about Uses of Simple Machines at Home. Today, we’re going to learn about Safety When Using Simple Machines At School.
Objectives
By the end of this lesson, you should be able to:
- Write 2 methods of using simple Machines at school safely.
Safety When Using Simple Machines at School
Safety when using simple machines at school is crucial to ensure the well-being of students and prevent accidents or injuries.
What is a Simple Machine?
A simple machine is a basic mechanical device that makes work easier. Some of the common simple machines include:
- Lever: A lever is a rigid bar that pivots on a fixed point called a fulcrum. It helps to lift heavy objects or move them with less effort. Examples include a seesaw, crowbar, and bottle opener.
- Pulley: A pulley is a wheel with a groove that helps to change the direction of force and reduce the effort needed to lift objects. Examples include a flagpole, crane, and elevator.
- Wheel and Axle: A wheel and axle system consists of a wheel attached to a rod called an axle. It helps to move objects over a surface with less friction. Examples include a bicycle, car, and wagon.
- Inclined Plane: An inclined plane is a sloping surface that helps to move objects up or down with less effort. Examples include a ramp, slide, and staircase.
- Wedge: A wedge is a triangular tool that helps to split or separate objects. Examples include an axe, knife, and chisel.
- Screw: A screw is a spiral-shaped device that helps to fasten objects together or move them with less effort. Examples include a screw, bolt, and drill bit.
Methods of Using Simple Machines at School Safely
There are many ways to use simple machines safely at school. Some of these methods include:
- Always seek guidance from the teacher before using any machine. This is important because the teacher can provide instructions on how to use the machine safely and can supervise the students while they are using it.
- Do not touch moving parts of the machines while they are in use. Moving parts can be dangerous and can cause injuries.
- Always wear the appropriate safety gear. This may include gloves, safety glasses, or other protective gear, depending on the machine being used.
- Read and understand the instructions on the simple machine before operating the machine. This will help you to use the machine correctly and safely.
Evaluation Questions
