Extreme Weather - Wind Power

Extreme weather

Measuring weather.

Definitions:

1. Typhoon: A tropical storm in the region of the Indian or the Western Pacific Ocean.
2. Monsoon: A seasonal wind in the region of the South and South East Asia. 
3. Anemometer: An instrument/tool for measuring the speed of the wind, or of any current of gas.
4. Beaufort wind scale: The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
5. What is it when a weather is really nice and turns to hail?  Climate Variability.

MATERIALS

1. 2 sticks 

2. Tape

3. Pencil

4. 4 cups

5. pin

6. Sticky notes

  

STEPS

1.   Collect Materials.
2.   Tape the 2 sticks together to form a cross.
3.   Tape the sticks onto the Cups.
4.   Get the Pin and stick it through the sticks and through the rubber of the Pencil.

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 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.	Field	20
2.	Old J block	15
3.	Grass hill	10
4.	Tennis court gate	3

CONCLUSION:

On the field, the Anemometer would spin 80 times per minute. The wind scale reaches about 13-20 kilometres per hour and the Beaufort force reaches to 3.


At the Old J block, the Anemometer would spin 60 times per minute. The wind scale reaches about 51 -60 kilometres per hour and the Beaufort force reaches 7.

On the Grass hill, the Anemometer would spin 40 times per minute. The wind scale reaches about 40 - 50 kilometres per hour and the Beaufort force reaches 6.

At the Tennis Courts, the Anemometer would spin 48 times per minute. The wind scale would reach 6 - 12 kilometres per hour and the Beaufort force would reach 2.
