Wind Power


  Hello, again. It's been 2 weeks, so I'm still gonna get used to this, AGAIN.
               - Me


   Measuring weather.

Definitions:


  1.  Anemometer: An anemometer is a device used for measuring wind speed and direction.
  2. Beaufort wind scale: The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. 

Anemometer

MATERIALS 

  1. 4 dishes
  2. 2 sticks
  3.   cellotape
  4.   pencil
  5.   pin

STEPS

  1.  Go to one of the designated areas.  
  2.  Raise the anemometer as high as you can reach.
  3.   Time 15 seconds.
  4.   Count the spins within 15 seconds.
  5.   Record.
Groups size: 5 
Roles:
  • Timekeeper - Taylor
  • Counter - ME
  • Recorder - Kade
  • Anemometer Manager - JC
  • Wind Manager - Jaren
  1. Mount the anemometer in a place that has full access to the wind from all directions.
  2. When the time keeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
  3. Repeat the above step four (4) times and record the number of spins on the chart.

FINDINGS

  • Record how many times it spins and record it in the table below.
  • You will need to time them and count the number of spins.


Place name on school grounds                                    Number of Spins in 15 seconds
1.Field1
2.Old J Block Site1
3.Small hill in Quadrangle1
4.Tennis Court Gate2

CONCLUSION:

 There was almost no wind in the field, the old J Block, and the grass hill in the Quad because the wind was very calm. The tennis court gate had the strongest wind of 2 spins/hr because the wind was slightly stronger than the other 3 areas and that the space nearby was creating a wind tunnel.
