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.

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.

Hurumanu - Renewable Energy

Aim: To make a solar-powered oven.

Materials: 

1.   cello tape (tape)
2.   tin foil
3.   pizza box
4.   black plastic or black paper
5.   vivid
6.  ruler  
7.   stick
8. newspaper
9. glad paper
10. scissors
11. chocolate biscuit
12. marshmallow

Steps:

1.   get the materials 
2.   get scissors and cut a square in the middle of the box at the top.  
3.   put a tin foil at the top of the square you cut and tape it.
4.   put the glad wrap at down the square where are the hole and tape it
5.   get a plastic or paper in black and tape the inside the box
6.   get a paper or a newspaper and make them like a frame inside the box.

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.

Section 4: Renewable Energy in the future.

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

wind power

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.
