Measuring weather.
Definitions:
- Anemometer: an instrument for measuring the speed of the wind, or of any current of gas.
- Beaufort wind scale: The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale
- typhoon: A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones.
- monsoon:Monsoon is traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation, but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea
- what is it when the weather is really nice and turns to hail:As the article explains, hail formation occurs "when strong currents of rising air, known as updrafts, carry droplets of water high enough that they freeze." The higher these droplets get, the cooler the temperature, even during a hot summer. ... In fact, warmer weather might actually result in a stronger updraft.
MATERIALS
- 2 sticks
- 4 cups
- sellotape
- pencil with eraser at bottom
- pin
- sticky note
STEPS
- Get your materials
- Put your 2 sticks in a cross shape
- Put your four cups on the end of the sticks (2 on each stick)
- Tape the cups
- Tape the sticks in place
- Get a pencil and a pin
- Pin goes in the rubber of the pencil through the tape
Group Investigation.
Groups size: 5
Roles:
Groups size: 5
Roles:
- Timekeeper
- Counter
- Recorder
- Anemometer Manager
- Wind Manager
- Mount the anemometer in a place that has full access to the wind from all directions.
- 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.
- 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.
CONCLUSION: I learned that there is so many different wind speeds for different places
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 |
- 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 field because its open
WHICH IS THE CALMEST AREA AND WHY?the tennis court gate because it is sheltered with trees
WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL? in a big open area
CONCLUSION:
I really enjoyed this research and investigating all of the different parts of wind and i all so learnt the amount of wind in different places of my school.
