Fossil Fuels

Hurumanu - Fossil Fuels.

 

Aim: To look at how fossil fuels are contributing to climate change and how we can prevent this.

Definition of Fossil Fuels:

a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.

Scientific Terms for Students

• coal: a dark-brown to black solid substance formed naturally from the compaction and hardening of fossilized plants and used as a fuel primarily for electricity generation
• natural gas: a mixture of hydrocarbon gases that occurs naturally beneath the earth’s surface and is used as a fuel primarily for cooking and heating homes
• renewable resource: a resource that is never used up (e.g., solar energy)
• non-renewable resource: a resource that is not replaceable after its use (e.g., coal, gas)

Examples of Fossil Fuels:

1.   Coal
2.  Natural Gas  
3.  Oil

Activity: 

In groups of 3 you will learn about different fossil fuels and the way they are mined?
Each group will be given a fossil fuel. The recorder will read it to the group. The recorder will write down some of the important points.
Person 1: Recorder: to write down 5 points of interest from the text. 

1. 5 Points:
2. Positives and negatives of your type of mining.

Person 2: Reporter: to read back to the class their 5 points of interest.
Person 3: Collector: Gathers the required stationary from the teacher.

Mining Fossil Fuels

What Fossil Fuels are mined?
How are they mined?

1. Digging
2. Scraping
3. Exposition  buried recourses

4. Drilling 

Where are they mined?

1. Underground
2. surface mining is relatively easy; shovels and bulldozers are effective at extracting coal near the surface.
3.  A hole is drilled into a potential oil patch and the oil is pumped out through a long tube.
4. Scientists look for gas and oil deposits with special equipment that causes a vibration in the ground as certain frequencies are associated with oil and gas.
5.Fossil fuels emit carbon dioxide when burned, a gas that traps heat below the earth's atmosphere.

Activity;

On the sheet provided you need to make two drawings of your cookie. 
1. looking down at it. 
2. side on -  of the imaginary habitat that will live on the top of the cookie. ( trees, buses, flax, sea, etc)

Material:

1.  Toothpick
2.   Cookie
3.   plate
4.  hands

Steps:

1.   get a chocolate chip cookie and place it on a plate
2.   Get a toothpick 
3.    start picking out the chocolate chips
4.   Pick them out until they are all gone

Findings: What did you find out as a result of your mining? that there is certain places where you can mine

Conclusion: Mining destroys the animals and plants that live on the earths surface.
