What Is Windmill?
A windmill is defined as a machine that is used to trap the wind to convert it into electrical energy. It is also used to grind grains to flour and to pump water.
How To Make A Windmill?
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.
- Heavy construction paper
- 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!
