Hurumanu-Renewable Energy

Aim: To make a presentation that investigates different renewable energy's.

1. Hydro Energy - The Energy is generated through hydropower depends on the water cycle which is operated by the sun, this makes it a renewable power source making it a more reliable source other than fossil fuels that are quickly being wasted.


2. Solar Energy - Solar Energy is luminous light and heat from the sun that is harnessed using a reach of technologies such as solar heating & Solar Panels. It is a renewable resource, 

it is obtained from the sun's rays. Solar energy is transformed immediately to electricity through a solar photovoltaic panel. Solar rays are collected off reflective surfaces and heats an object to process it that creates solar thermal energy.

3. Wind Energy - Wind Power or Wind Energy is operated by the wind to provide it to function and make power through wind turbines to turn electric generators, it can do other work like milling or pumping. Wind power is sustainable and renewable energy and has a much smaller impact on the environment compared to burning fossil fuels.

4. Wave Energy - Wave power is generated by the up and down motion of floating devices placed on the surface of the ocean, Let's say that wind produces waves and waves produce energy, it is also renewable energy. As the waves travel across the ocean, very high-tech devices capture the physical movements of the ocean currents and the flow to generate power. 

This energy can be used to run turbines and there are plenty of places where the winds are strong enough to produce continuous wave movements or motions.

1. Type: Hydro
2. Is it used in NZ ? Hydropower is used in New Zealand
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.

Hurumanu-Wind power

Extreme weather

Measuring weather.

Definitions:

1. Anemometer: An instrument for measuring the speed of the wind.
2. Beaufort wind scale: The Beaufort scale is to measure relating to the wind to see the conditions in the sea or/and on land.

MATERIALS  

1. Pencil w/rubber on top  
2.   x1 Pin
3.   x2 Long sticks
4. x4 Cups
5. Sellotape
6. Scissor

STEPS

1. Put the stick on top of each other in an X shape and tape it in the middle.
2. Get a pencil and put the X shape on top of the rubber of the pencil and pin it together through the tape of the X.
3. Tape all the cup at the end of each end of the X so that can catch the wind.
4. Take it outside and it should start catching wind... if there is any and depending on how strong it is. 

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

We found that on the Field it was an open space but there was no wind at all and we got "0" spins in 15 secs, the old J block site was removed but has an open space and enough wind to go past, but unfortunately there was no wind and there were "0" spins in 15 secs, we were not sure what was happening. Whether the Anemometer was the problem or there was just no wind, we weren't sure but we did our best to make it at least go in the whole spin. We went to the new artificial grass hill area to see if we can get wind there, but the same results were coming over and over again. Once we moved to the Tennis Court gate there was a difference, we got a little breeze and it had much more wind power to make it spin all the way and we got "1" spin-in 15 secs.

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	0
2.	Old J Block site	0
3.	Grass hill in quad	0
4.	Tennis Court gate	1

CONCLUSION:

The wind was calm and did not produce that much wind to make the Anemometer spin all the way around to call it a full spin, the Anemometer was unstabled between the rubber of the pencil and the pin connected to the rubber. We were given a comment from a gym teacher we should have added a small straw between them to make it more stable and catch more wind.
