Science - 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?

Pacific Island, New Zealand (Different places near the sea)

What else do we need to think about?

Where you live, Where to build houses,

What other places around NZ will be affected?

Auckland - Har bour, Lion rock, Nelson, Bay of islands and more

What does this do to our drinking water?

Salt water, Sea level rise

What are the main concerns?

1.  One of the main concerns are where to build your houses as the sea level rise can floud those houses  
2.  The second one is that we will stat to get salt water into our drinking system.

What can we do to prevent climate change?

What can we do?

1.  Build our houses away from the sea
2.    STOP plastic

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 
2.   Solar heating
3.  Transport

What are 3 others you can think of?

1.  Walk
2.   Cycle
3. recycling

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

Conclusion







Aim: To make a presentation that investigates how renewable energy's are turned into electricity.

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:hydro
2. Is it used in NZ ? no 
3. Other Countries that use it? yes other countries (china,Brazil,Canada and the United state.
4. How is it used to generate electricity? Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. ... As the water flows down through the dam its kinetic energy is used to turn a turbine. The generator converts the turbine's mechanical energy into 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

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

Science - Pizza box

Aim: To make a solar powered oven.

Materials: 

1.  pizza box
2. tinfoil
3. tape
4. black plastic
5. newspaper
6. glad rap
7. straw
8. scissors
9. marshmallow/biscuit

Steps:

1:cut out the flap on the pizza box so that it is 5cm around the edge.

2:sellotape some tinfoil on the inside of the flap

3:sellotape some glad-wrap so that the hole you have cut on the pizza box lid is covered over with glad wrap 

4:put a piece of black plastic on the bottom of inside of the pizza box on the bottom 

5:make a paper square that fit inside the pizza box and lays around the edeg
6:put a marshmallow on the top of the chocolate biscuit, place it on the plastic plate and put it in the solar oven 
7:put is in the sun to cook

Science - climate change

 Aim to learn about the different emission of  climate change


Cows>methane is a greenhouse gas that is 25 time more powerful then carbon dioxide.

Food>trains,planes,trucks add carbon dioxide to the atmosphere

Landfill>are landfill is growing and using more of healthy land.

Transport> most car need gas or diesel to work

electricity>electricity is a from of of energy used to power almost everything in our homes

factories> making clothes cars electronic and processed food create a lot of pollution

Science - Decompistion

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 quad<	10
4.	Tennis Court gate	3

• USING A,4 PAPER DRAW YOUR RESULTS ON A GRAPH.
• TAKE A PICTURE OF THE GRAPH AND UPLOAD IT TO YOUR BLOG

1 WHICH IS THE WINDIEST AREA AND WHY?

2 WHICH IS THE CALMEST AREA AND WHY?

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

1. The field is the windiest as the cars come past and make a lot of wind plus its a big space.
2. The Tennis court is the calmest as its all fenced off and there would be very little wind.
3. The best place to build a windmill would have to be the old J block site because people won't be over there most of the time and it's also out of the way of the children
