  • Air pushes the blade and the blade makes power.
  • The bigger the blade, the more it catches.
  • You can see it working from far away.

You can love wind in St. Paul.

What it really is

A wind turbine converts moving air into rotation and then into electricity.

Three things to try today

  1. Make a pinwheel.
  2. Change the blade shape and try again.
  3. Say which shape spun faster and why.

For the grown-up reading this

St. Paul is one of the cities the Minneapolis–St. Paul–Bloomington, MN-WI metro area is officially named after. Somewhere in that number is a kid who lights up about wind and has never met another one.

Blade shape versus speed is a fair test with one variable. That is the whole scientific method.

If the kid who loves this is a girl
