Wind Power- Science

Extreme weather

Measuring weather.

Definitions:

Typhoon means: Typhoon is a tropical storm that is really strong in indian or western Pacific oceans. 

Monsoon means: Monsoon is a seasonal prevailling wind and the season of the southwest monsoon in India and adjacent areas that is characterized by very heavy rainfall. 

Anemometer means: Anemometer is an instrument for measuring the speed of the wind, or of any current of gas.

Beaufort wind scale: Beaufort wind scale is an empirical measure that relates wind speed to observed conditions at sea or no land.

MATERIALS 

1. 2 Sticks  
2.  Four cups
3. Pencil  
4. Pin 
5. Cellotape
6. Sticky Note
7. Scissors.

STEPs

1.  Get all of your materials from the teacher.   
2.  Tape the 2 stick together into a cross
3.  Tape the 4 cups to the end of the sticks  
4.  Put the pin into the middle of the 2 sticks  
5.  pin the pencil together
6.  Put your sticky note onto one of the 4 cups

Group Investigation.

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 site	15
3.	Grass hill in quad	10
4.	Tennis Court gate	3

CONCLUSION:

This week in Science we have been focusing on Wind power. Wind power is how the wind is so powerful that can break anything like for a example it can break cars and window and also there are different kinds of powerful winds. One of them are Typhoon, Typhoon is a tropical storm that is really strong in indian or western Pacific oceans. For science we had to be in a group of 5 and in my group was Anneleise, Bailey, Janel and Khaylanie and then all of us had to make a Anemometer.

On the Field there are 80 spins per minute,13-20 wind speed and 3 beautfort scale. In the old J block there are 60 spins per a mintue, 51-61 wind spped and 7 beautfort scale. On the Grass hill there are 40 spins per a mintue, 40-50 wind speed and 6 beautfort scale. On the Tennis court gate are 12 spins per a mintue, 6-12 wind speed and 2 beautfort scale. In my conclusion the field has the highest spins.

Wind

Beaufort Wind Scale

Beaufort Force	Wind Speed (KPH)	Spins	Indicators	Terms Used in NWS Forecasts
0	0-2	0	Calm; smoke rises vertically.	Calm
1	2-5	10	Shown by direction of wind smoke drift, but not by wind vanes.	Light
2	6-12	40	Wind felt on face, leaves rustle; ordinary vanes moved by wind.	Light
3	13-20	80	Leaves and small twigs in constant motion; wind extends light flag.	Gentle
4	21-29	130	Raises dust and loose paper; small branches are moved.	Moderate
5	30-39	190	Small trees in leaf begin to sway; crested wavelets form on inland waters.	Fresh
6	40-50	250	Large branches in motion; whistling heard in telephone wires; umbrellas used with difficulty.	Strong
7	51-61	320	Whole trees in motion; inconvenience felt walking against the wind.	Strong
8	62-74	390	Breaks twigs off trees; generally impedes progress.	Gale
9	75-87	470	Slight structural damage.	Gale
10	88-101	550	Seldom experienced inland; trees uprooted; considerable structural damage occurs.	Whole gale
11	102-116	640	Very rarely experienced inland; accompanied by widespread damage.	Whole gale
12	117 or more	730+	Very rarely experienced; accompanied by widespread damage.	Hurricane

Based on your findings what was the Wind Speed and the Beaufort Wind Force for each area.

	Spins per minute	Wind speed ( kph)	Beaufort Scale

Old J Block site	60	51-61	7
Grass hill	40	40-50	6
Tennis Court Gate	12	6-12	2
