I'll solve this worksheet by identifying each simple machine shown in the images. Let me go through each one systematically.
First, I need to understand what the six types of simple machines are according to the key at the top:
1. Pulley
2. Inclined Plane
3. Wheel/Axle
4. Screw
5. Wedge
6. Lever
Now I'll examine each image and match it to the correct simple machine type.
Starting with the first row:
Image 1 (Roller coaster): This is an inclined plane. The tracks create slopes that allow the cars to move up and down.
Image 2 (Soap dispenser): This appears to be a lever. The pump mechanism typically works as a lever when you press down on it.
Image 3 (Dump truck): The wheels of the truck represent a wheel and axle system.
Image 4 (Bottle with cap): The bottle cap is a screw. It has threads that allow it to be twisted on and off.
Moving to the second row:
Image 5 (Ladder): A ladder is an inclined plane. It creates a sloped surface to reach higher places.
Image 6 (Log with axe): The axe blade is a wedge. It's designed to split wood by concentrating force on a narrow edge.
Image 7 (Wedge-shaped object): This is clearly a wedge, used for splitting or holding things apart.
Image 8 (Skateboard): The wheels of the skateboard represent a wheel and axle system.
Third row:
Image 9 (Axe): Again, the axe blade is a wedge.
Image 10 (Bicycle): The bicycle has multiple simple machines, but primarily features wheels and axles.
Image 11 (Scissors): Scissors are levers. The handles act as levers to apply force to the blades.
Image 12 (Flagpole): The flagpole uses a pulley system to raise and lower the flag.
Fourth row:
Image 13 (Screw): This is clearly a screw, with its threaded shaft.
Image 14 (Seesaw): A seesaw is a classic example of a lever.
Image 15 (Water faucet): The handle of a faucet typically operates as a lever.
Image 16 (Clothesline with pulleys): This uses a pulley system to raise and lower the clothesline.
Let me now provide the complete answer:
Row 1: Inclined Plane, Lever, Wheel/Axle, Screw
Row 2: Inclined Plane, Wedge, Wedge, Wheel/Axle
Row 3: Wedge, Wheel/Axle, Lever, Pulley
Row 4: Screw, Lever, Lever, Pulley
Parent Tip: Review the logic above to help your child master the concept of simple machines worksheet middle school.
