The water cycle heaxagons

The water cycle

Today for science we have been learning about the water cycle the task that we were given was to cut out some hexagons to do with the water cycle and put them in order of where they are meant to go.
The water cycle is made of evaporation, Transpiration, Precipitation, Condensation and Water vapour.

Issues of climate change

For science today we have been learning about climate change today aim was to learn about the different activities that contribute to climate change here is a list of stuff contributing to climate change and why

1. Electricity:It 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
2. Factories: Making clothes, cars, electronics, and processed food creates a lot of pollution. When materials like plastic, card board, metal, and cement are made, harmful gases are released into the air and water.
3. Waste: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 are created, including 
4. Cows
5. Food
6. Transport

Solar energy experiment

Solar Energy

Aim: To find out which colour attracts the suns heat.

Hypothesis: I think the colour black will attract the most heat because If you wear black you heat up quicker than normal

Materials:

1. Black plastic
2.  White paper
3.  Silver tinfoil
4.  Water
5.  Cups
6. Thermometer

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	22	23	24
30	23	25	25
45	24	27	27

Conclusion: The Black plastic and the tinfoil are closely matched in heat.

Solar energy

Solar energy

For science we have been learning about solar energy our task was to cut out hexagons and put then in the right order the hexagons had writing on them to do with renewable energy then our second task is to compare solar energy to coal and see what is better on a 1-10 scale 

Comparing Coal energy with Solar energy ( Rate; 1 = poor to 10 = great)

Factor	Solar	Coal
Livability	10	4
Sustainability	10	2
Accessibility	9	1
Cost	$10,000-15,000	$34
Your choice...	Yes	Nope

Wind

Wind

For science today we went outside with our school made anemometers and tested how much wind certain areas had by seeing how many times the anemometers spins the places in school we went to was the field the old J block the tennis court the place and a hill  the place i and my group found the windiest was the hill because it was higher up. The hill had more wind but didn't do a full spin like the other places.

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	0
2.	Old J Block site	0
3.	Grass hill in quad	0
4.	Tennis Court gate	0

Wind power

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer:
2. Beaufort wind scale:

MATERIALS 

1. 4 Dishes 
2. 2 Kebab sticks  
3. Sellotape  
4. Pencil with a rubber on top
5. Pin  

STEPS

1. put the sticks together to form a t  
2.   On the end of the sticks put the dishes on facing the same way as the others
3.   The get your pencil and your pin
4.   Put the pin through the sticks and into the rubber
5.   Then go outside and test it
6. 
   

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 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.

4
Section 2: Definitions

Define and provide a picture of each energy type.

1. Hydro Energy:relating to or denoting the generation of electricity using flowing water (typically from a reservoir held behind a dam or barrage) to drive a turbine which powers a generator.
2. Solar Energy:radiant energy emitted by the sun.
3. Wind Energy:electrical energy obtained from harnessing the wind with windmills or wind turbines.
4. Wave Energy:power obtained by harnessing the energy produced by waves at sea.

2. Is it used in NZ ? Yes
3. Other Countries that use it? Nepal and others
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.

My Investigation on climate change

My Investigation on climate change

Acidification

Definition: Is where you ad acid to water

1. What is happening to the oceans? 

• Their collecting more and more carbon dioxide and becoming more acidic

2. What does this do to shellfish? 

• It is becoming harder for sea life to make their shells out of calcium and they are beginning to die.

HOW DOES CLIMATE CHANGE CONTRIBUTE TO THE ACIDIFICATION OF OUR OCEANS?

Methane gas is entering the water cycle and making the water and oceans become more acidified

DEFORESTATION

DEFINITION:You clear land to make way for farm's and other stuff

What are trees used for?

Wood,Furniture,Paper and other things

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

Deforestation affects the carbon cycle and water cycle because trees pull in the carbon dioxide and make it into oxygen and when it rains trees catch water then the water evaporates and the cycle starts again

ICE CAP MELT

DEFINITION: When all the ice of ANTARCTICA melts

If all the ice melted what would happen? The sea level would rise and the oceans would have less salt so then some sea life might die

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE? 

If the ice cap melts the sea level is going to rise and peoples home are going to be under water
