Science, hurumanu,

Definitions!!

Hi readers today I am going to be telling you about the document we did about definitions!
We got given 5 definitions then we had to say what it means.

here is mine:

hurumanu science-definition

1. Anemometer

Measures the speed of the wind, gas, or any current.

2. 
   Beaufort wind scale

Measures the wind speed

3. Python

It’s similar to a hurricane.

4. Monsoon

A Monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region.

5. What is it when the weather is really nice then turns to hail fast?

forms when thunderstorm drafts are strong enough to carry water droplets well above the freezing level. It’s a Hailstone

I hope you enjoyed reading my blog, if you have any feedback or positive comments.

Please leave it in the comments. Bye!!

Hurumanu - Wind Power

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer:
2. Beaufort wind scale:

MATERIALS   

1.   Sellotape  
2. pencil
3. pin
4. 2x sticks
5.   x4 cups
6. sticky note

STEPS

1. Sellotape both cups at the end of the sticks.
2. Sellotape the sticks together to make a cross.  
3. Pin the centre of the cross to the rubber of the pencil.

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 the quad	10
4.	Tennis Court gate	3

• USING A4 PAPER DRAW YOUR RESULTS ON A GRAPH.
• TAKE A PICTURE OF THE GRAPH AND UPLOAD IT TO YOUR BLOG

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

CONCLUSION:

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 the direction of wind smoke drift, but not by wind vanes.	Light
2	6-12	40	The 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 lose 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	80	13-20	3
Old J Block site	60	6-12	2
Grass hill	40	6-12	2
Tennis Court Gate	12	2-5	1

CONCLUSION:

This week I learnt how to make a wind gauge.

we found out that in the field's wind speed is 13-20 kph.

we also found out that the old J blocks wind speed is 6-15 kph.
