Science Hurumanu: Measuring Weather

Wind power|Conservation|Sustainability
              
         Extreme weather|Measuring weather

Definitions:

1. Anemometer: Is an instrument which measures the wind.
2.  Beaufort Wind Scale:  It is an empirical measure that relates wind speed to observe conditions at sea or on land. 

Materials:

1.  Sellotape
2.  Pencil
3.   2 Pencils
4.   4 cups
5.  Pin

Steps:

1. Sellotape the sticks to the cups
2. Sellotape the sticks together to make a cross
3. Pin the cross to the rubber on the pencil   

Group Investigation:

 Group Sizes: 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
1.	Field	20
2.	Old J Block site	15
3.	Grass hill in squad	10
4.	Tennis court gate	3

 WHICH IS THE CALMEST AREA AND WHY?

WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL?

Conclusion:

On the old J Block site, the Anemometer spun 60 spins per minute. It had a wind speed of 13-20 kph. This speed is 3 on the Beaufort Scale.

On the Grass Hill in the squad, the Anemometer spun 40 spins per minute. It had a wind speed of 2-5 kph. This speed is 1 on the Beaufort Scale. (Shown by direction of wind smoke drift, but not by wind vanes.)

On the Tennis Court gate, the Anemometer spun 12 spins per minute. It had a wind speed of 2-5 kph. This speed is 1 on the Beaufort Scale.

According to the data, the most spins on the Anemometer is on the field, with 80 spins per minute and it had a wind speed of 13-20 kph. The least spins on the Anemometer was by the Tennis Court gate, it spun only 12 spins per minute. It had a wind speed of 2-5 kph. 

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 kph	3
Old J Block site	60	13-20 kph	3
Grass hill	40	2-5 kph	1
Tennis Court Gate	12	2-5 kph	1

Solar Energy

Aim: To find out which colour attracts the sun's heat.

Hypothesis: I think that it the colour Silver or black with attract more sunlight than the colour white. 

Materials:

1.  Tin foil Plastic Cup
2.  Clear plastic Cup
3.  Black plastic paper
4.  White A4 Paper
5.  A4 sized foil 
6. Thermometer
7. Heat lamp
8. Plug for Heat lamp

 Steps

1.   Get your materials, set them up like the photo below.
2.  Plug in the heat lamp and place it facing in towards the cups.
3.  After 15 minutes measure each cup with a thermometer and record findings.
4.  After 30 minutes measure each cup with a thermometer and record findings.
5.  After 45 minutes measure each cup with a thermometer and find recordings.
6. 
   

Findings: Below is a photo of how we setup our experiment and also how it should look like, so on the left side we have our heat lamp set up in the middle, we didn't put the heat lamp close up to the cups as you can see in the photo. 

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	19.1	19	20
30	25	27	26
45	20	24.5	22.5

Conclusion:

Today in science we have started on a new experiment called Solar energy. I was in a group of four with Janel, Anneleise, and Rowina. We have to collect all of the materials that was needed for the experiment and had to record the temperatures of each of the cups. A tin foil cup, a white cup and a clear plastic cup covered with the black plastic. Overall it was a great experiment and lesson learning about solar  energy.

Climate Change Issues
 Aim: To learn about the different emissions of climate change.

• Cows: Cows create a greenhouse gas called methane when they burp or fart. Methane i a greenhouse gas that is 25 times more powerful than carbon dioxide. With about 1.5 billion cows around the world, methane is having a big effect on climate Change.
• Factories: Making clothes,cars , electronics, and processed food creates a lot of pollution. When materials like plastic, cardboard, metal, and cement are made, harmful gases are released in the air and water. 
• Transportation: Most cars need gas or diesel to work. These come from oil, which is a fossil fuel. The carbon dioxide in oil goes in the atmosphere when the car is running.
• landfill: Our landfills are growing and using up more healthy land. When waste breaks down in landfills, greenhouse gases are created, including methane and carbon dioxide. These gases contribute to climate change.
• Electricity: Electricity is a form of energy used to power almost everything in our homes. Electricity can come from renewable sources water, wind, sun) and non-renewable sources like fossil fuels (oil and gas). Fossil fuels release Co2 into the atmosphere. 

Self manager Blog Post

Self management is having the ability to regulate one's emotion, thoughts, and behaviors effectively in different situations. This includes managing stress and setting and working towards personal goals. I showed Self management by arriving to class prepared, starting the day with a "Can Do" attitude, paying attention, following instructions and working independently without distractions. Below is a DLO showing ways we could self manage ourselves aswell as our learning.
