Extreme weather

Measuring weather.

Definitions:

1.  Anemometer:
2. Beaufort wind scale:

MATERIALS

1. 1 rubber pencil  
2.   4 small plastic round disc
3.   1 pin 
4. tape  
5.  2 sticks 

STEPS

1.   tape up the plastic round disc with the stick x4
2.   tape up the 2 sticks together
3.   put the pin through the tape
4.   let the pin go into the rubber on the pencil 
5. put tape on the pin mack suer that is tight

Groups size: 5 
Roles:

• Timekeeper
• Counter
• Recorder
• Anemometer Manager
• Wind Manager

1. Mount the anemometer in a place that has full access to the wind from all directions.
2. When the timekeeper 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

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	1.5
2.	Old J Block site	0
3.	Grass hill in quad	0
4.	Tennis Court gate	0

CONCLUSION:  

the windy place was on the field the spins have over to 1.5, with the highest one in all four places, the reason why I think the field was the windy place was that at the field has no trees and high staffs around, the reason why the others place was all 0 was that there have no wind, and the reason why the field was the highest was that the field has not high staffs and trees around, because thye high staffs can block the wind
