Science Week 1 - Wind Turbine

Extreme weather

Measuring weather.

Aim: To test the wind to see how you would test the wind

Definitions:

1. Anemometer:
2. Beaufort wind scale:

MATERIALS

1. 2x sticks  
2. Cello Tape
3. Pencil  
4.   4x cups
5. Pin
6. Sticky note
7. Scissors

STEP

1. Collect materials
2. Tape the 2 sticks together to form a cross  
3.   tape the sticks onto the cups
4.   plug the pin through the tape
5.   stick the pin into the rubber of the pencil
6. then write your names on a sticky note and stick it onto your Anemometer

Group Investigation.

Groups size: 5 
Roles:

• Timekeeper ( watch)

• Counter

• Recorder ( Chromebook or refill )

• Anemometer Manager ( Anemometer)

• Wind Manager

Instructions:

• Go to the measuring place and set up your wind gauge.
• Make sure everyone in your group is ready to start their roles.
• Record how many times it spins and record it in the table below.
• Count the number of spins in 15 seconds.
• Record it on your chart.

FINDINGS

	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 a wind power and how reporters tell how the weather is going to be. We had to be in a group of 5, in my group I was with Amanda, Latoiya, Bianca and Keghan.  We have made a wind power source that we are going to test in the areas above and with that we will be recording the number of spins. We have been focusing on the graph below on what the we found. There is a bit of maths that is in there but I had a little help, (Not by Cheating). This week with science was more complicated tan I had expected. I always love challenging myself aswell.

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
Field	16	6-12	2
Old J Block site	10	2-5	1
Grass hill	5	0-2	0
Tennis Court Gate	3	0-2	0

WHICH IS THE WINDEST AREA AND WHY?

WHICH IS THE CALMEST AREA AND WHY?

WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL?

1. The field is the windiest as the cars come past and make a lot of wind plus its a big space.
2. The Tennis court is the calmest as its all fenced off and there would be very little wind.
3. The best place to build a windmill would have to be the old J block site because people won't be over there most of the time and it's also out of the way of the children
