Worksheet 2: Simple Machines
---
1. Place the name of each simple machine under its image.
We are given six images and six names:
Names:
- wheel
- wedge
- lever
- pulley
- ramp
- screw
Now, let’s identify each image:
1.
First image (top left): A box on a slanted surface → This is an
inclined plane, which is called a
ramp.
-
✔ Answer: ramp
2.
Second image (top middle): A spiral-shaped object with a head → This is a
screw.
-
✔ Answer: screw
3.
Third image (top right): A circular object with spokes → This is a
wheel.
-
✔ Answer: wheel
4.
Fourth image (bottom left): A long bar balanced on a fulcrum with weights → This is a
lever.
-
✔ Answer: lever
5.
Fifth image (bottom middle): A triangular shape → This is a
wedge.
-
✔ Answer: wedge
6.
Sixth image (bottom right): A system of ropes and wheels → This is a
pulley.
-
✔ Answer: pulley
####
✔ Final Answers for Part 1:
- Top row:
ramp,
screw,
wheel
- Bottom row:
lever,
wedge,
pulley

2. Match the simple machines and their definitions.
We have:
Machines:
- Wheel
- Ramp
- Lever
- Pulley
- Wedge
- Screw
Definitions:
- To lift and lower objects more easily.
- To move things along the ground.
- To move objects along an inclined surface.
- To hold something in a place.
- To lower and raise very heavy objects.
- To break something apart.
Now, match them correctly:
1.
Wheel → Used to reduce friction and move things along the ground.
➤
To move things along the ground.
2.
Ramp → An inclined plane that helps move objects up or down gradually.
➤
To move objects along an inclined surface.
3.
Lever → A bar that pivots around a fulcrum to lift or move loads.
➤
To lift and lower objects more easily.
4.
Pulley → A wheel with a groove for a rope; used to lift heavy loads.
➤
To lower and raise very heavy objects.
5.
Wedge → A tool that splits or separates materials (e.g., axe, knife).
➤
To break something apart.
6.
Screw → A spiraled inclined plane; holds things together or lifts material.
➤
To hold something in a place.
