How to make a Windmill

Windmill

Objective

Make a toy or model windmill for your windowsill or garden and learn about the fundamentals of wind energy first-hand. Wind turbines produce electricity by using the natural power of the wind to drive a generator. The wind is a clean and sustainable fuel source, it does not create emissions and it will never run out as it is constantly replenished by energy from the sun.

Materials Required

  • Heavy construction paper
  • Pencil
  • Ruler or compass
  • Scotch Adhesive Putty
  • Straw or thin stick
  • Scotch Precision Scissors
  • Push pin or metal paper fastener

Procedure to build the Windmill

  • Roll a 1-inch piece of adhesive putty into a ball in your hands. Set it aside.
  • Cut construction paper into a square shape. (If your paper is 8 ½ x 11, then cut 2
    ½ inches off the long end.)
  • Fold the paper diagonally to form a triangle. Unfold and then fold diagonally in
    the other direction, forming another triangle. When you open the paper you’ll see
    the creases form an “X”.
  • Use a ruler or compass to measure 1 inch from the center of the X. Mark this
    measurement on all four lines with a pencil.
  • Cut along each line to the pencil mark.
  • Now pull the four corners to the center, folding the tips of the facing triangles over
    each other evenly.
  • Push a pushpin or metal fastener carefully through the center of the paper. Make
    sure it goes through all four corners and pokes out through the back.
  • Stick the ball of putty on top of your straw or stick. Then stick the end of the pin
    or fastener into the putty.
  • Now blow on your windmill and watch it spin!
