Materials:
- Sellotape
- Scissors
- Pizza box
- Straw
- 3 Marshmallows
- 3 chocolate thins Biscuit
- Glad Wrap
- Tinfoil
- Black Plastic
- Ruler
- Vivid
- Newspaper
Steps:
- Cut out the flap on the lid of the pizza box so that it is 5cm around the edge
- Sellotape some tinfoil on the inside of the flap
- Sellotape some glad wrap so that the hole you have cut on the pizza box lid is covered over with glad wrap
- Get a square peice of black plastic and sellotape in the inside of the bottom of the box
- Get news paper and screw it up into a roll shape and make 4 so it is on each side inside the box. Get one of the newspaper roll and put them inside the box on the side. Do the same with the other 3.
- Get a straw and put it onto of the flappy bit and on the glad wrap inside
- Inside the newspaper rolls put a plastic plate and put inside
- Get your 3 biscuits and put inside
- Get your 3 marshmallows and put on top of each biscuit
- Make sure you write your name on with vivid

Conclusion:
A few weeks ago we have been learning about renewable energy. Then we had to watch a video on how o make a solar powered oven and then we had to make it ourselfs. it took a few hours because we had to wait a while for some sellotape and everyone had to use it. There are the materials and the steps on how to make it above.
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.
- Hydro Energy - Hydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed. Kinetic energy is the energy of motion
- Solar Energy - radiant energy emitted by the sun.
- Wind Energy - electrical energy obtained from harnessing the wind with windmills or wind turbines.
- Wave Energy -
Description
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter.
Section 3; Investigate each of the 4 Energy types.
( Hydro ,Solar ,Wind ,Wave )
- Type: Hydro
- Is it used in NZ ? Yes it has
- Other Countries that use it? Albania, Paraguay, Congo, Nepal, Namibia, Zambia, Tajikistan, Norway, Ethiopia, Kyrgyzstan
- How is it used to generate electricity? Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
- 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.
Less global warning
Public health
Inexhaustible energy
Jobs and other economic benefits
Stable energy prices
Reliability and resilience
The solar foundation
Renewable electricity Future study
National renewable energy laboratory
Union of concerned scientists
