In the weekend

Tody in period 3 our teacher Mrs Hastie said that we are going to write a 300-word story for this period. Then Mrs Hastie wrote some things on the board to choose to write about and I choose to write about the weekend.

This weekend I am going to Hanmer Springs with one of my friends called Tyson we are going on Saturday. Tyson is going to scooter to mine then I’ll get my mum to drop me and Tyson off to his house and do something before we have to go and watch his sister play softball for 30 minutes or longer. Once that is done we will get going to Hanmer Springs it will take us a while to get there so me and Tyson are going to do stuff to pass the time. When we get there we are going to go to the pool where you have to get a raft and go down in circles then you go down a tube then go straight then it’s finished then we are going to try and go on the new hydro slide a few times then we will go on some other ones.

Wind Power

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer: An instrument for measuring the speed of the wind, or of any current of gas.
2. Beaufort wind scale: This scale is used to relate wind in the sky to wind on land or in the sea.
3. Typhoon: A tropical storm in the region of the Indian or western pacific ocean.
4. Monsoon: The rainy season accompanying the wet monsoon.
5. What is it when the weather is really nice and it turns to hail: climate variability.

MATERIALS   

1. 2 Sticks

2. 4 cups

3. Sellotape

4.pencil with an eraser on the  bottom

5. pin

6. sticky note
7.Scissors

STEPS

1.   Stick the cups to each end of the sticks
2.   Tape the sticks together to make a cross
3.   Pin the cross to the rubber of the pencil

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 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.FINDINGS
3. 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? The windest area in the school is the field because it was the most open area out of the four.

   WHICH IS THE CALMEST AREA AND WHY? The calmest place that we tested was the tennis court gate because it was the most inclosed because of the trees in the way.

   WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL? The best place to build a windmill is in an open area because it will have the most wind compeared to a place that has trees all around it.

   

   
   
   
   
   

   CONCLUSION:TODAY IN SCIENCE WE ARE LEARNING ABOUT THE BEAUFORT WIND SCALE WE DID SOME TESTS TO SEE WHAT PLACE HAD THE MOST WIND  THE FIRST PLACE WE DID WAS THE MIDDLE OF THE FIELD THE ORIGINAL SPIN PER 15 SECONDS WAS 20 SPINS THEN WE HAD TO TIMES BY 4 AND THAT IS 80 SO THEN WE HAD TO  LOOK AT THE CHART AND FIND 80 ONCE WE FOUND IT WE HAD TO FIND THE WIND SPEED AND PUT IT ON A CHART THEN WE MOVED ON TO THE OLD J BLOCK AND THAT ONE WAS 15 SPINS AND THEN TIMES BY 4 TO MAKE IT 60 THEN WE HAD TO DO THE WHOLE PROCESS ALL OVER AGAIN FOR THE  OTHER  ONES WHERE THE GRASS HILL AND THAT WAS 10 SPINS THEN  TO 40 AND THE LAST ONE  WAS THE TENNIS COURT GATE THAT WAS 3 SPINS THE ONE WITH THE MOST SPINS WAS OBVIOUSLY` THE MIDDLE OF THE FIELD BECAUSE IT WAS THE MOST OPEN SPACE OUT OF THE FOUR THE LEST ONE WAS THE TENNIS COURT GATE BECAUSE IT HAD THE TREES BLOCKING THE WAY.

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 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	80	13-20	3
Old J Block site	60	2	0
Grass hill	40	6-12	2
Tennis Court Gate	12	10-20	1

CONCLUSION: TToday in science we are learning about the Beaufort wind scale we did some tests to see what place had the most wind  the first place we did was the middle of the field the original spin per 15 seconds was 20 spins then we had to times by 4 and that is 80 so then we had to  look at the chart and find 80 once we found it we had to find the wind speed and put it on a chart then we moved on to the old j block and that one was 15 spins and then times by 4 to make it 60 then we had to do the whole process all over again for the  other  ones where the grass hill and that was 10 spins then  to 40 and the last one  was the tennis court gate that was 3 spins the one with the most spins was obviously` the middle of the field because it was the most open space out of the four the lest one was the tennis court gate because it had the trees blocking the way.
