Hurumau-Climate Chaos

Climate Chaos

Written by:Qyn

Title	Solar Energy
Aim	To see what colour attracts more sun heat.
Hypothesis	I think the colour silver will attract the sun.
Materials	white paper white cup  black plastic 1 clear cups Black plastic cover tin foil   Cup covered in tin foil heat lamp  100ml cup of water Thermometer  Timer
Steps	Collect all of the materials  Put the white paper on the table Put the white cup on top of the paper Put black plastic on the table next to the white paper  Put the cup on the black plastic cover  Put the clear cup in the centre of the plastic Put the tin foil next to the black plastic  Cover the clear cup with tin foil Put the heat lamp in front of the cups
Data/Findings	Time  Cup 1 White Cup 2 Black Cup 3 Tinfoil 0 16 degrees  16 degrees  16 degrees  15 19.1 degrees  19 degrees  20 degrees  30 25 degrees  27 degrees  26 degrees  45 20 degrees  24.5 degrees  22.5 degrees  The first 15 min the temperature of the white cup is 19.1 degrees.  The next 30 mins the temperature of the black cup is 19 degrees. On the 40 mins timer, the temperature of the tinfoil cup is 20 degree.
Conclusion	In conclusion, my findings in this experiment state that the colour attracts the heat more. The colour white attracts less heat. We found out that solar panels are coloured black because black attracts more heat. In other hot countries, they don’t paint their houses black because they don’t want to be hot, so they paint their houses white.

Hurumau-Renewable Energy

Hurumanu - Renewable Energy

Aim: To make a solar-powered oven.

Materials: 

1. Pizza box 
2. Tinfoil
3. Glad wrap
4. Straw 
5. scissors
6. Marshmallow
7. Ruler
8. vivid marker
9. Black plastic
10. Biscuit
11. Sellotape

Steps:

1. Cut out the flap of the pizza bow so that it is5 cm around the edge.
2. Sellotape some tinfoil on the side of the flap.
3. Sellotape some glad wrap so that the hole you have cut out on the pizza box lid is covered over with glad wrap.
4. Put a piece of black plastic on the inside of the pizza box on the bottom.
5. Scrunch up 4 newspaper to make a square that is surrounding the black plastic.
6. Sellotape a straw under the flap and on the pizza lip so the flap is opens
7. Put the marshmallow on top of the biscuit, place it on the plastic plate and put is in the solar oven.
8. Put is in the sun to Cook.

Conclusion





Aim: To make a presentation that investigates different renewable energy's.

Section 1: Title Page

Make a title page that incorporates all renewable energy 's Hydro, Solar, Wind and Wave.

                                                                                                                                                       
Section 2: Definitions

Define and provide a picture of each energy type.

1. Hydro Energy
2. Solar Energy
3. Wind Energy 
4. Wave Energy

Section 3; Investigate each of the 4 Energy Types.
(Hydro, Solar, Wind, Wave ) 

1. Type:
2. Is it used in NZ?
3. Other Countries that use it?
4. How is it used to generate electricity?
5. Draw and label a diagram of the main parts of the electricity generator? This can be done on paper and uploaded or on a drawing program on your device. I do not want any Internet images or pictures. They must be hand-drawn using a ruler and labelled.

1. Section 4: Renewable Energy in the future.

List 10 ways that renewable energy will be used in the future to replace our current activities.

2. Beaufort wind scale:

MATERIALS   

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.

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 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?

WHICH IS THE CALMEST AREA AND WHY?

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

CONCLUSION:

Wind

Beaufort Wind Scale

Beaufort Force	Wind Speed (KPH)	Spins	Indicators	Terms Used in NWS Forecasts
0	0-2	0	Calm; smoke rises vertically.	Calm
1	2-5	10	Shown by the direction of wind smoke drift, but not by wind vanes.	Light
2	6-12	40	The wind felt on face, leaves rustle; ordinary vanes moved by wind.	Light
3	13-20	80	Leaves and small twigs in constant motion; wind extends light flag.	Gentle
4	21-29	130	Raises dust and lose paper; small branches are moved.	Moderate
5	30-39	190	Small trees in leaf begin to sway; crested wavelets form on inland waters.	Fresh
6	40-50	250	Large branches in motion; whistling heard in telephone wires; umbrellas used with difficulty.	Strong
7	51-61	320	Whole trees in motion; inconvenience felt walking against the wind.	Strong
8	62-74	390	Breaks twigs off trees; generally impedes progress.	Gale
9	75-87	470	Slight structural damage.	Gale
10	88-101	550	Seldom experienced inland; trees uprooted; considerable structural damage occurs.	Whole gale
11	102-116	640	Very rarely experienced inland; accompanied by widespread damage.	Whole gale
12	117 or more	730+	Very rarely experienced; accompanied by widespread damage.	Hurricane

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	3
Old J Block site	60	6-12	2
Grass hill	40	6-12	2
Tennis Court Gate	12	2-5	1

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.
