Magnetic Straw Windmill Science Experiment

Instructions

Materials:

• Straw (1 piece)

• Magnets (2 small magnets)

• Paper (cut into a windmill shape)

• String (about 10 cm)

• Tape

• Scissors

Steps:

1. Create the Windmill: Cut the paper into the shape of a windmill. You can choose to have four or more blades depending on your preference.

2. Set up the Straw: Fix the straw vertically on a table using tape. Ensure one end of the straw is securely taped down so it stands upright.

3. Attach the Windmill: Tie the paper windmill to the top of the straw using a string. Make sure the windmill can spin freely.

4. Add Magnets: Place small magnets on both sides of the windmill. By adjusting the distance of the magnets, you can control the speed of the windmill's rotation.

5. Start the Experiment: Gently spin the windmill and observe how the magnets influence its movement.

Principle:

The magnets' attraction affects the windmill's motion. As the windmill spins, the magnetic field generated by the magnets either accelerates or slows it down. This is a simple way to demonstrate the relationship between magnetic fields and object movement.
