Hurumanu - wind power

Measuring weather.

Definitions:

  1.  Anemometer: An instrument for measuring the speed of the wind, or of any current of gas.
  2. 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
  3. Monsoon: A seasonal prevailing wind in the region of South and SE Asia, blowing from the south-west between May and September and bringing rain.
  4. Typhoon: A tropical storm in the region of the Indian or western Pacific oceans.
  5. what is it when the weather is really nice and turns to hail: it is called climate variability because the weather can instantly change to anything.

Anemometer


MATERIALS
 

  1. two sticks
  2. four cups
  3. four strips of sellotape
  4. one pin
  5. one pencil with an eraser at bottom 
  6. one sticky note

STEPS

  1. Tape the cups on each end of the stick x2.  
  2. make a cross when you have done.
  3. stick a pin through the rubber at the top 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.
  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.

  • 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 it has a cold climate there
WHICH IS THE CALMEST AREA AND WHY? the tennis court gate because there is a lot of friction stopping it
WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL? up high in the hills.

CONCLUSION: In science today we have been learning about wind. we have made some bar graphs about how strong the wether is in some place of the school, the wind is many different in different places because there are different strengths of wind everywhere in the school. sometimes the wind can be powerful but most of the time it is pretty average weather. the original spins per 15 seconds on the field was 20 the hill was 10 the old j block site was 15 and the last is tennis court gate it is 3 because of all the trees around it is stopping it from making the wind so powerful. the one that had the most speed out of all of them was the field reaching at 20. the second-highest was the old j block site reaching at 15 almost 20.

3D designer

This morning Our teacher Mrs Allen showed us our CIP taskboard where it shows different activities that we can choose to do for a few hours. The activity that I have chosen is, Use TinkerCad to create a 3D model of your dream house and garden. Use google to get some inspiration for your house. Mrs Allen said it is very fun to do and you can build whatever you want but it takes a bit of time to get used to. So my friends and I went off and started to make our dream house, I didn't do much because It was hard to get used to and I was talking to my friends too much. It was very cool one of my favourites is that you can move a box in the top left corner and you can move it around to see all around the thing that you have made. 

An hour later our teacher aid took a group to plant some trees at the back of the field so we can make a big forest. I am a year 8 now and the teacher aid said that it will be fully grown when I am a year 13. The teacher aid name it Mark and he is very good at growing things and he knows every plant. After we went to the back of the field and he told us how to plant the trees. Then we got a spade and then we put some garden gloves on so our hands didn't get dirty, so we got a plant and dug a hole and big as a normal-sized bucket. Then we squeezed the bottom of the tree so it could come out of the container because all plants come in a container. Once it came out we squeezed the bottom so the roots and spread out. In the whole there were alot of big giant worms, HuHu Grubs and maggots it was disgusting. When I was digging up the hole there was a piece and I thought it was a kind of bone but it was a bit of a tree. After we squeezed the roots we put it in the middle of the hole and then we put the loose dirt around it. After everyone got a turn we packed up to go to class and now we are doing this blog.

Here are 2 photos of the taskboard and the house that I have made. The house is not my dream house it is a plain and simple just to show you what you can do. You can also change the colours of the things you have made.
