Solar Energy

Solar Energy

Aim: To learn about how solar energy is used. 

Hypothesis: I think that silver will attract the most heat because, when the light shines on silver it will reflect on it. 

Materials:

1. White Paper 
2.  Styrofoam Cup (X2)
3.  Clear Cup
4. Roll of Tinfoil 
5. Black plastic
6. Lamp
7. Thermometer

Steps

1. Gather all materials.  
2.  Put down some paper, tin foil and a piece of black plastic on the table.
3.  Wrap some tin foil on one styrofoam cup. 
4.  Cut a circle piece of black plastic and wrap around a clear cup.
5.   Put each cup on eat coloured material. etc. Black, white and silver.
6. Set down lamp and face towards cups. Make sure lamp is on.
7. Wait every 15 minutes and use thermometers to record the temperature. 

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	20	23	20
30	21	23	21
45	21	23	22

Activity:

In pairs rate the livability of coal vs solar energy.

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

Factor	Solar	Coal
Livability	10	4
Sustainability	10	2
Accessibility	10	3
Cost	1	9
Your Choice...	Yes	No

Conclusion:

1.  solar is a renewable item because this helps us to make electricity by not killing the coal and you can reuse the solar because the son will keep going for a billion of years and we can still save the earth.
2.  The sun, water, and wind can help us to make energy because here in New Zealand we use water so we have energy and wind can help us make the windmill spins and the solar energy can get energy from the sun
3. in our other experiment the black make heat and this is 
4. The wind is a renewable energy because it does run out.
5. It costs more to my coal rather than solar power. 
6. Solar is better than coal because solar can live up to billions of years

THE ZERO WASTE

The Zero Waste Climate Solution movie 

Video questions:

What has human activity done to our planet?
They keep creating greenhouses gasses and we kept creating carbon dioxide and some of the waste we don't reuse them. If we didn't act fast our future will get worse 
What is Zero Waste?
Definition: one of the quickest and cheapest ways a community can immediately reduce climate impact.

What stuff has a carbon footprint?
CarWhat are 2 easy things to help our planet?

1.   Recycle
2.    Use less electricity

What do we need to recycle?

1. We need to recycle old phone or recycle them.
2. We need to recycle plastic bottles. 

What does recycling do to our planet?
It reduce less waste abd we could make our planet into a better place.

How much of our rubbish is made up of food scraps?
A lot, because a lot of people eat and throw there food scraps at the rubbish bin.

What does methane gas do to our planet?
It makes our planet 3x hotter than carbon dioxide.

What does soil do to carbon dioxide in the atmosphere?
Soil can actually help suck thecarbon dioxide

What do using zero waste practices do to our planet?
It could help our planet to make our climate change, global warming, reduce less landfill and our waste.

What is a carbon footprint?

What is your Carbon Footprint?

Carbon Footprint Calculator

You are now going to look at your own carbon footprint by taking a questionirre. Remember to 'Add details to improve accurcay'.

Based on the questionaire what is your:

1. Ecological Footprint - 6.3

2. Carbon Footprint - 54

How many planets did you have?

 3.7 planets.

Climate Chaos - Climate change and the future.

Aim; To look at the different ways we can prevent climate change in the future.

How is sea level rise going to effect us in NZ

What places will be effected?

The coast area, lakes, near the beaches, homes, buildings, cities, sea, and rivers.  

What else do we need to think about?

stop using fossil fuels and start using renewable energy and going to public transport. 

What other places around NZ will be affected?

The coast and where floods always been through.

What does this do to our drinking water?

When the seawater rises the saltwater comes up and effect our  drinking water

What are the main concerns?

1. Sea level rising  
2. Icecap melting

What can we do to prevent climate change?

What can we do?

1.  we can use public transport 
2.    stop using fossil fuels
3.     stop cutting trees

Curbing climate change

What is the one, silver bullet solution?

There is no silver bullet.

What is the mix of things we need to start doing?

1. renewable energy   
2.   public transport
3. using less energy 

What are 3 others you can think of?

1.   the 3 R's
2.  planting tree  
3.  stop using fossil fuels.

Colour 1: for actions they are already doing 

Colour 2: for actions that they pledge to undertake in the future

Ecological Handprint The Ecological handprint builds on the concepts from the Carbon Footprint. We will look at the positive actions of:

1. Transportation
2. Community
3. Consumption
4. Water
5. Food
6. Home
7. Waste
