Background Information(for facilitator)
• Almost all forms of energy require some sort of fuel. A fuel is anything that is used for energy. When we hear the word fuel, we usually think of gasoline, oil, wood, and other substances that burn or combust.
• Most of the energy we use comes from the burning of coal. Coal forms when the remains of plants are partially decomposed and buried under sediments. As more and more sediments pile up, pressure and temperature increases, driving off methane and carbon dioxide. This is part of a process known as carbonization, which eventually leads to the formation of coal. In contrast, oil and natural gas deposits form when microorganisms and plants die in shallow lakes and seas and settle to the bottom. This decomposing organic matter is then buried by sediments and subjected to increased temperature and pressure, eventually forming oil and natural gas.
• The technology for nuclear energy is largely the result of the development of nuclear bombs that began during World War II. the first bombs that were created were fission bombs—they released vast amounts of energy by causing a chain reaction in which the nuclei of heavy atoms were split in a process known as fission. Later, even more powerful bombs were made by causing nuclei of heavy atoms to combine in a process known as fusion. A nuclear power plant uses the same concepts that lead to fission reactions, but at a much slower, controlled rate.
• Wood has been burned as a biofuel for centuries. Wood is an “energy storage device” because trees use and store energy from the sun. Ancient plants and animals store the same type and energy and become fossil fuels. Plant material that is often considered waste can also provide energy when broken down to create steam, or liquid fuel. Ethanol is a form of liquid biomass that is added to gasoline as a way to reduce the amount of fossil fuels used in cars.

Notebook Reflection
Describe two things that you learned about either
fossil fuels or nuclear energy that you did not know
before today.
Do you believe it is worth the effort of collecting
biomass from everyday garbage in order to use it for
fuel?
