Transcript of Wind Speed

Wind Speed Protocol Make an anemometer by following the steps provided 1. Cut off the rolled edges of 4 paper cups to lower their weight 2. Color the outside of 1 of the 4 cups a different color that the others 3. Create two cardboard stirps into exactly the same length 4. Cross them so they make a (+) plus sign & staple them together 5. Using a ruler and a pencil and draw lines from the outside corners of where the cardboard strips cross (The spot where the lines cross is the middle) 6. Staple the cups to the cardboard, 1 on each end corner 7. Push a pin through the middle of the plus sign 8. Attach the cardboard plus sign to an eraser point on the pencil used in step 5 9. Blow on the cups to make sure they spin 10. Put molding clay on the unused side of the pencil to hold the anemometer straight. 11. Place it in an open area outside such as an empty field 12. count how many times the colored cup goes around in a single minute Here's a picture of a scientist-made anemometer Here's a picture of a home-made anemometer Science Behind Wind Speed Measurements... *Wind speed is important for turbines to generate energy. *Wind turbines require an average wind speed of 14 mph to generate electricity. Yay! there's a presentation next door!! Zoom! let's go!!! *Knowing the wind speed helps tell the amount of energy generated. The, Anemometer... *The term comes from the Greek word anemos, meaning wind *They measure the wind's velocity and measure the wind's pressure. *One simple type is the cup anemometer invented in 1846 *Another type is the windmill or propeller anemometer Thanks For Watching!!!
