1

What is coal?




2

Read the flood story in Genesis 6-8 and relate the events as outlined in the story to how coal was formed. How does the Genesis flood account compare to other theories on the formation of coal and discuss in small groups assumptions that each theory needs to make and your opinion on the theories.




3

Why is coal called a fossil fuel? What are other fossil fuels and why is it important to conserve fossil fuels and explore renewable fuels/energy sources? How much does your local electric company rely on fossil fuels?




4

Define the following units of heat:




5

List three of the major uses of coal today and three major historic uses of coal.




6

List three advantages and three disadvantages of using coal as a fuel.




7

List four major environmental impacts of coal use. What methods can be used to mitigate them?




8

Describe at least three surface mining methods and three subsurface mining methods that are used to extract coal. Research and identify the type of coal mining method nearest to your home.




9

Discuss three major hazards of underground coal mining and what is done to reduce them.




10

Collect pictures or specimens and be able to identify the four main types of coal:



10a

Lignite coal




10b

Anthracite coal




10c

Subbituminous coal




10d

Bituminous coal





11

Know the characteristics of each of the four main types of coal, including: percentage of carbon; color range and appearance features; primary uses; BTU (kJ) content; areas where mined; and other facts of interest.




12

Obtain at least one specimen of coal.



12a

Study and record as many observations as you can concerning the specimen(s) you have, including color, hardness, flakiness, etc.




12b

Using the knowledge gained in this honor, identify the coal type.




12c

Try lighting a chunk of coal with a lighter or match. How easily can the specimen(s) be lit in comparison to other combustible materials?




12d

Grind the material into a powder and repeat the experiment. What were the results?





13

Do one of the following:



13a

Tour a coal mine and have a group discussion on what you learned.




13b

Visit a coal mining museum and have a group discussion on what you learned.




13c

If there is no coal mine or museum nearby, watch a video on the mining of coal and have a group discussion on what you learned.





14

Memorize Romans 8:28. Discuss how bad events in your life, or of someone you know, has provided fuel for better things, in much the same way that the flood in Genesis created coal.
