How to Put Anemometer Cups Back On

Weather, from rain to snow, offers a visual look at science in action. In fact, weather can teach children about a myriad of ideas, such as speed and force. Wind is a weather action that can be measured with a simplistic paper cup design called an anemometer. Anemometers demonstrate the strength of wind through spinning. Four paper cups are aligned in a windmill pattern, attached to a center point paper cup by 4 separate straws. The anemometer spins horizontally in reaction to the passing wind. Students can observe and record wind speed data by watching the anemometer spin. However, the cups may become loose, requiring a simple repair.

Straws

Instructions

Repairing The Anemometer
- 1
  Anemometer cups adhere to the attached straws with staples. As a result, cups that have broken off the straw length will have damaged the straw also. Remove the damaged straw from the anemometer's center point by using a staple remover.
- 2
  Attach a new straw to the center point by stapling it firmly to the centralized cup in the middle.
- 3
  The straw secures to the cup by entering the cup's side through a punched hole slot. Remove the old straw and staple attachment from the fallen cup. Slide the cup onto the new straw through the previous hole punch area. Make sure to align the cup so that its open end faces the bottom end of the adjacent cup.
- 4
  Staple the straw's end to the cup's interior wall with the stapler. For added strength, staple the straw and cup twice.
- 5
  Place the anemometer back in the wind and test for durability.
