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.

  1. Image result for anemometer
    Beaufort wind scale
Measures the wind speed
  1. Python
It’s similar to a hurricane.

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

  1. 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.

Hurumanu - Wind Power

Extreme weather

Measuring weather.

Definitions:

  1.  Anemometer:
  2. Beaufort wind scale:


AnemometerMATERIALS   

  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. 
  4.

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 quad10
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:

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.
