Science Worksheets for Grade 6: Investigating Wheel and Axle

Investigating Wheel and Axle
How does the wheel and axle work?

Materials:

• Thick shoe box
• String
• Pencil
• Match box
• Paper clip
• Tape

What you need to do:

1. Remove the cover and the base of the shoe box. Be sure that the frame is strong. Bore two holes about 2 inches from the top of the box and put the pencil through.
2. Make a mark in the center of the pencil and tie a cord or string to it. If you want a counter weight, place a stone in a small plastic and tie it with cord.
3. Stretch paper clip and attach it to the end of the pencil. Bend it into shape to serve as a handle of the wheel and axle.
4. Using the scotch tape or strong adhesive tape, wind the handle to the axle so as not to slip it.
5. Attach a small box to serve as a cart of your freight.
6. Wind the wheel and axle. Now you have a model of a freight elevator.
7. Observe the function of the wheel and axle in the model.

What have you found out?

1. Which is the wheel and axle in the model?
2. How does the wheel and axle work?
3. How does counterweight work when the freight goes up and down?

Conclusion:
Make a conclusion based from the given problem.
