Step 1: Set Up the Base
Use a tall glass or cardboard tube to hold your wind turbine upright. Insert a wooden dowel or straw through the tube to act as the turbine’s axle.
Step 2: Make the Blades
Cut blades out of cardstock or plastic using a template. Punch a hole at the bottom of each blade for attachment.
Step 3: Attach the Blades
Secure the blades onto the straw or skewer, ensuring they can catch the wind when air blows on them.
Step 4: Add the Lifting Mechanism
Tie a piece of string to the axle and attach a small paper cup or hook at the other end. Place a small object inside the cup, such as a paperclip or LEGO piece.
Step 5: Test the Wind Turbine
Place the turbine in front of a fan or blow on it. Observe how the wind turns the blades, rotating the axle and pulling up the object.

How Wind Turbines Work
Wind turbines work by harnessing the movement of air to create rotational motion. The spinning blades turn a rotor, which is connected to a shaft. This shaft spins a generator, which produces electricity. The amount of energy produced depends on several factors:
- Wind speed: Faster wind creates more energy.
- Blade size and shape: Longer or more aerodynamic blades can capture more wind energy.
- Number of blades: Most modern wind turbines have three blades to balance efficiency and stability.
- Blade angle (pitch): The angle of the blades can affect how much wind energy is converted into motion.
💡 Engineers use physics and aerodynamics to design turbines that maximize energy capture while minimizing resistance. This experiment allows kids to explore these real-world engineering concepts in a simple way.
