  • Now let’s look at another type of fossils. FossilFuels
  • Remember the three fossil fuels are:coal crude oil natural gas
  • Fuels are things that burn.Which of the following burn?a. paperb. waterc. woodd. iron
  • Paper and wood burn but waterand iron don’t.Therefore, paper and wood could fuelsbe called ______.Yes, they are called fuels butNOT fossil fuels.Why?
  • Because fossils are theremains of things that lived longago.Coal, crude oil and natural gaswere formed from organismsthat lived long, long ago.
  • Formation of Fossil FuelsSo coal, crude oil and natural gas arecalled “fossil” fuels because theyformed froma. plasticb. cast and moldsc. sediment such as gravel, sand, silt and clayd. remains of ancient plants and/or animals
  • How is coal formed?
  • Heat and pressureturned the deadplants into coal (http://www.need.org/

  • Below is a website that has good readingmaterial that you can print (in black andwhite) on fossil fuels and alternative energysources such as wind, solar, biomass andgeothermal.Under the tab student choose EnergyInfobooks. Both the Complete Primary andElementary Energy Infobooks are excellent.So are the individual printouts on eachenergy source such as coal, petroleum,natural gas, wind, solar, etc. (http://www.need.org/)
  • Another useful website.From the tabs at the top of the pagechoose,The Energy Story. Under the Table ofContents, you will be able to choosechapters on the fossil fuels and alternativesources of energy. http://www.energyquest.ca.gov
