Use this website to complete the refinery diagram worksheet. Be sure to look at the relationship between temperature, pressure and the length of the hydrocarbon chain. Be sure to hit the "forward"button for each of the refined products to see what they are used for.

In order to use the "cradle to grave" approach for oil, you need to know:

• the source material;
• the extraction process;
• what each of the refined products are made of (elements);
• the energy inputs of the refining process;
• the sector of use;
• the result of use (combustion products for example).

Review this video in order to use the "cradle to grave" approach for coal, you should be able to answer the following:

• the source material;
• the extraction process (mining);
• the 4 types of coal;
• what is coal used for/the sector of use;
• the result of use (finished products for example).

Check out this website. It illustrates from extraction to burner, the story of natural gas. Be sure to take the quiz at the end of your tour (lower left of the list) to see how you score compared to the national average. As before, check out the following

• the source materials;
• the extraction process and/or the conversion processes;
• what each of the refined products are made of (elements);
• the energy inputs of the refining/conversion process;
• the sector of use;
• the result of use (combustion products for example).

For all of the above fossil fuels, 

1. what do you think about the way that these materials are being used? 
2. Are they highly specialized or can they be used for multiple applications? 
3. Does the level of specialization make them more or less valuable? 
4. List the ways that you have interacted with each of the resources so far today.
