Measuring weather.

                                   Definitions:    1 anemometer: 

2 Beaufort wind

4 Monson 

5 What is it when the weather is really nice and turn to hail?

3 Typhoon  A typhoon is essentially a hurricane. Just called a typhoon in the north western pacific. ... A typhoon ( hurricane) is an intense storm of tropical origin. A monsoonare seasonally directed winds that are common in eastern and Southern Asia. During winter, strong cooling produces a shallow high pressure over Siberia.

1.  Anemometer:
2. Beaufort wind scale:                                                             

MATERIALS

 

1. 2 sticks       
2.                                                 4 cups 
3.                                                sellotape 
4. pencil with eraser at bottom 
5. pin 
6. sticky note   

STEPS  

1.   
2. Get your materials
3.   put your 2 sticks in a cross shape
4.   put your four cups on the end of the sticks (2 on each stick)
5.   tape the cups
6.   tape the sticks in place 
7. et a pencil and a pin
8. pin goes in 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 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

2.	old J block site	15
3.	Grass hill in quad	10
4.	tennis court gate	3
