Students learn little from the experience of snapping  pre-made and pre-designed propellers and wind turbine rotors onto their projects. We wanted them to learn through inquiry and experimentation; designing, testing and re-designing. What did we find?  Students absolutely love to build their own rotors/propellers, and learn an amazing amount from it.

The kit come with a hub that mounts directly to dowel. The hub can attach 1-to-6 blades.

Plenty of extra skewer sticks are included for alternate blade designs and experimentation. For short blades, bamboo project sticks can be used instead of skewers.

You will need to supply recycling bin materials and tape for the blades.

Use these on air boats, air racers, hover-craft, fans, mini wind turbines, and other inventions.
