Hello, young learners! Welcome back to Primary 1 Basic Science & Technology. In our previous lesson, we learned about Simple Machines in the House. Today, we’re going to learn about Storage and Care of Simple Machines.
Objectives
By the end of this lesson, you should be able to:
- List 3 ways of caring for simple machines
- List 2 methods of storing simple machines
Storage and Care of Simple Machines
Storage and care of simple machines refer to the practices and measures taken to ensure the proper maintenance of simple machines when they are not in use.
What is a Simple Machine?
A simple machine is a basic mechanical device that changes the direction or magnitude of a force. Some of the common simple machines include:
- Lever: A rigid bar that pivots on a fixed point called a fulcrum. Examples include a seesaw, crowbar, and a bottle opener.
- Pulley: A wheel with a groove that helps change the direction of a force. Examples include a flagpole, crane, and a well pulley.
- Wheel and Axle: A wheel attached to a rod called an axle. Examples include a car wheel, bicycle wheel, and a doorknob.
- Inclined Plane: A flat surface that is at an angle to the horizontal. Examples include a ramp, a slide, and a staircase.
- Wedge: A triangular tool that is used to split or separate objects. Examples include an axe, a knife, and a chisel.
- Screw: An inclined plane wrapped around a cylinder. Examples include a screw, a bolt, and a jar lid.
Ways of Caring for Simple Machines
There are several ways to care for simple machines to ensure they function properly and last longer. Some of these include:
- Clean the machines regularly: Dust, dirt, and debris can accumulate on simple machines and hinder their movement. Regularly cleaning them with a soft cloth or brush helps remove these particles and prevent wear and tear.
- Check the machines regularly for any fault: Regularly inspecting simple machines for any signs of damage, wear, or loose parts is crucial. This allows for early detection and repair, preventing further damage.
- Handle simple Machines with care to avoid damage: Rough handling can cause scratches, dents, or breakage. It’s important to handle simple machines gently and avoid dropping or throwing them.
- Apply lubricant to the moving parts of simple machines regularly: Lubrication reduces friction between moving parts, preventing wear and tear and ensuring smooth operation.
- Always follow the safety guidelines when operating any simple Machine: Each simple machine has specific safety guidelines that should be followed to prevent accidents and injuries.
Methods of Storing Simple Machines
Proper storage of simple machines is essential to prevent damage and keep them organized. Some of the methods include:
- Keep simple Machines in clean and dry environments: Moisture and humidity can cause rust and corrosion, damaging the machines. Storing them in a clean and dry place helps prevent this.
- Use labelled containers to store simple Machines: Labelled containers help keep simple machines organized and easily accessible. It also prevents them from getting mixed up with other tools or equipment.
- Store simple Machines in proper places to avoid strains on them: Storing simple machines in a way that avoids strain on their moving parts helps prevent damage and ensures they remain in good condition.
Evaluation
Now that you’ve learned about Storage and Care of Simple Machines, let’s see if you can answer these questions:
- What are three methods of caring for simple machines?
- Name two ways of storing simple machines.
- What are some examples of simple machines?
- Why is it important to care for simple machines?
Conclusion
Remember, taking care of simple machines is important for their longevity and proper functioning. By following the methods discussed, you can ensure that your simple machines stay in good condition and serve you well for a long time.
