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

Acidification

Hey guy, so we are learning about thing what is happening around the earth like climate change pollution and more. the thing that we are learning today is about Acidification from ocean and trees.

My Investigation on climate change

ACIDIFICATION

DEFINITION: 

The definition of acidification is the process of acid being aded to the water.

What is happening to the oceans?

• The oceans absorbs the carbon we use and thats good for us people but for our ocean, animals  and trees this will destroy our trees ocean and more.
• Carbon dioxide effect the ocean and the sea animals/life and how they grow.
• Living things at the ocean is getting affected by the acid.

What does this do to shellfish?

The shellfish can't create new shells.

The acid affect the sea animals and the seashells can't build it owns seashells.

The seashells are no longer to build its shell due to the oceans acidification. 

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

Climate change contributes with this of water cyclye and the sun is getting closer, and if the sun if the sun get closer the icecap melts and the sea level will rise and the people who is next to sea, lake beach, can have some flood at their cities and more. The fishes who need sea water will die becasue the ice is a fresh water and some fish don't need fresh water and they can die.

DEFORESTATION

DEFINITION:

Definition is the Process of cutting trees like 

what are trees used for?

They are used for some equipements like chairs table and more or 

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

This effect climate change because if there is no trees the carbon dioxide won't be suck in and the ocean will get the carbon and the shells won't completely build it shells.

2 Images;

ICE CAP MELT

DEFINITION:

The ice will melt from artartica and this will not help our our countries 

If all the ice melted what would happen?

• There will be less salt water and some fishes will die
• Some countries will sink down and will be forgotten

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?

This could drown some countries fishes will die and we will have less land.

Water Cycle

AIM: TO LEARN ABOUT WATER ON EARTH.

Definition:

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• Transpiration. Evaporation from plants.
• Condensation. When water vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
• Acidification: the action or process of making or becoming acidic.

THE WATER CYCLE SONG

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

1.  blue food colouring
2.  ziplock bag
3.  water
4.   a permanent pen 
5. blue food colouring
6.  ziplock bag
7.  soda
8.   a permanent pen 
9. baking soda/baking powder

Steps:

1.  draw some mountain and about the water cycle
2. when finish add water
3. food colouring 2 drops
4. zip it sticks it at the window  
5. wait for a week and see what happened 

Two Images:

Findings:

	The Water Cycle	Acid Water Cycle
Does it cycle?	1	1
Amount of Water	2	1
Acidity	0	1

Key: Water and acidity amount: 0 = none 

1 = small 

2 = large 

Other comments:

The water cycle did cycle, it has a large amount of water and no acidity.

The Acid  water cycle did cycle it has a small amount of water and a small amount of acidity  

Conclusion:

The water was evaporating was evaporating every night and every time we come to the class room or at the staat of morning. This experiment was fun because you can learn how to know how or why there is water evaporation, this expirement makes me think of climate change because there is a lot of things happening at the world and the water, Like icecap melting and plastic the sea animals eating plastic. So thats why I think we are learning this because a lot will happen if the sea and water got damage and the trees will not grow if there is no water. 

Climate Chaos - Climate change and the future.

Extreme weather

Measuring weather.

Definitions:

1. Anemometer:
2. Beaufort wind scale:

MATERIALS  

1. 4 Dishes  
2.   2 Sticks
3.   Tape
4.   Pin
5.   Pencil  

STEPS

1.   Grab all the materials.
2.   First Stick the 4 dishes to each side of the stick. Make sure the dishes are opposite sides.
3.   Secure with tape.
4. Stick the middle of the sticks together, make sure it is secured tight.  
5. Stick a pin through the tape and into the top pencil. Make sure the tape isn't on the pencil so it could spin right. 
6. Experiment with the wind. 

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	11
2.	Old J Block site	0
3.	Grass hill in quad	0
4.	Tennis Court gate	1

• 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:

the field has many spins because it has an open space. the old j block site have a 0 wind because of the trucks or the fences. the grass quad has 0 wind as well I think its because of the building around it like the new Kahui is blocking the wind. the tennis court has 1 spin I think because of the trees at the metal fences and i think this is why it only has 1 spin.

By The River

So this reading we are learning to infer our reading. inferring means reading between the lines, I never heard it before but that's why we are learning it. inferring is like the author giving you the information about the story without really telling you like, for example. Daisy is a cow. "how many legs those cows have". So the author gives you information.

Here is the example or picture of the meaning of inferring.

 The assignment that we are given is we have to write inferring and the literal. The literal is like the information is already there. So the story that my group has been given is called "By The River" the story is about a girl who has been with frend with Chloe but they never hang out. so our teacher gave us 5 information of inferring and 5 literal. 

This subject is kinda fun to do because you have to find a lot of information and this make you challenge yourself and this makes you know the story very well, and I like things like this because this challenge me, but it was kinda frustrating because sometimes you won't find the answers thats why we are learning this kind of stuff.

Asking questions?

Hello guys, so last week we are doing asking and answering questions. So we have to know why do we have to ask and answer questions. Why? Because we need to know if we really know the story or understand the story well. for example...

Our teacher gave us a partner to do this and we have to ask a question to our partner if they really do understand the story well. Doing this make me know the story well and asking questions are really good so you would know and understand  what is the story is about.

Decomposing

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think the bananas will decompose faster because if you unpeeled the banana and you leave it, it will get rotten fast. 

Materials:

1.   bread
2.   test tube
3.   white styrofoam
4.   paper
5.   banana
6.   stand for the test tube
7.  rubber stopper
8.  water

Steps:

1.   get 4 test tubes and 1 test tube stand
2.   cut the banana, bread, styrofoam, and cardboard so this fit at the test tube  
3.  put the banana and etc. at each test tube
4.   put the rubber stopper at the top of the test tube.
5.   wait until change.
