Renewable Energy- Science

Aim: To make a solar powered oven.

Materials: 

1.   Ruler
2.   Scissor
3.   Marshmallow
4.   Newpaper
5.   Tin Foil
6.   Glab Wrap
7.   Pizza Box
8.   Black Paper
9.   Straw
10.   Selltape
11.   Biscuit
12.  Vivd Maker

Steps:

1. Cut out thr flap on the lid of the pizza box so that it is 5cm around the edge.
2. Selltape some tinfoil on the inside of the flap
3. Selltape some glad-wrap so that the hole you have cut on the pizza box lib 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 fits inside the pizza box and lays around the edge.
6. Put a marshmallow on top of the chocolate biscuit, place it on a plastic plate and put it in the solar oven.
7. Put it in the sun to cook.

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.

I have done my title page on paper.

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 Energy- Hydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. 

Solar Energy- Solar energy is the term used to describe the light and heat produced by the sun. Solar power is the conversion of sunlight into electricity.

Wind Energy- Wind energy refers to capturing the energy from moving air, wind and converting it into electricity. 

Wave Energy- Wave energy is the transport and capture of energy by ocean surface waves and the energy captured is then used for all different kinds of useful work, including electricity generation, water desalination, and pumping of water.

1. Is it used in NZ ? 

Hydro/Wind - New Zealand has excellent renewable electricity resources. We've got hydro, wind and geothermal up the wazoo. In a typical year, more than 70% of our electricity comes from renewable sources, and the government wants this to increase to 90% by 2025 (for non-dry years).

Wave- yes. New Zealand is very fortunate in its wave energy resource.

Solar- I don't know.

1. Other Countries that use it?

Hydro- Yes, There are other countries that have hydro power such as China, Canada, Brazil, the United States and Russia, they also have big land masses.

Solar- Yes,  China, United states, Japan, Germany, India, Italy, United Kingdom and Australia have Solar Energy. 

Wind- Yes,  France, Canada United Kingdom, Spain, India, Germany, United States and China have Wind energy.

Wave-  Yes,The Western coasts of Scotland, Northern Canada, Southern Africa, Australia, Northwest Coast of United States and particularly Alaska have Wind energy.   

1. How is it used to generate electricity?
2. 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.
