give me one example  of  a  fossil  fuel?

Fossil Fuels are all (in chemical terminology) hydrocarbons.  One example is of a hydrocarbon is propane, C3H8.  When a hydrocarbon reacts (combusts) with the air it ALWAYS produces Water and Carbon Dioxide.  C3H8 + O2 ---> 3*CO2 + 4*H2O

conventional means mainstream or those that most people use\nSo in general, fossil fuel - oil, gas, coal is what most of the world uses today.\nNonconventional could include solar, wind and even more exotic sources like ocean waves.  Another example is thermal energy such as what Iceland has done - also check out their new plans to totally avoid fossil fuel by going to fuel cell.

Fossil Fuels have been more valuable because of the war at Middle East which is centered at Iraq which holds a lot of oil (which is a main fossil fuel) at Middle East. Government have made solar panels, hydroelectricity dams, and wind turbines to reduce the use of fossil fuels. Fossil Fuels have a negative impact on the environment because it causes global warming.

Try a museum of natural science.  You can find all kinds of fossils there.

From so many chemical reactions you couldn't list them all here but if you mean in the context of the global warming issue we need only look at systems that release carbon that would otherwise be locked away into the environment.  The big two sources are the much talked about burning of fossil fuels.  The carbon of coal and oil are burned to form mostly CO2.  Another big source that I don't hear much about is the carbon in limestone (calcium carbonate).  We heat this up to realize a lot of CO2 to make concrete.  A lot of CO2 is released in this process.  From the limestone and from the fossil fuel used to cook it.

Tell them to bring in working models of "alternate forms of energy".  It might be a little tricky because some of the stuff is flamable.....but I remember having this fair in third grade and it was a great learning experience.  One kid brought in a giant 5 gallon jar half full of pig crap and then showed how it emits gas that could then be used in a combustion engine.  Amazing.  But think...obviously solar...there's got to be the electric type motors....models of combustion engines are going to come in using the corn oil approach etc.

Coal, oil and gas are called "fossil fuels" because they have been formed from the organic remains of prehistoric plants and animals. \n\nCoal provides around 28% of our energy, and oil provides 40%. \n\nBurning coal produces sulphur dioxide, an acidic gas that contributes to the formation of acid rain. This can be largely avoided using "flue gas desulphurisation" to clean up the gases before they are released into the atmosphere. This method uses limestone, and produces gypsum for the building industry as a by-product. However, it uses a lot of limestone. \n\nCrude oil (called "petroleum") is easier to get out of the ground than coal, as it can flow along pipes. This also makes it cheaper to transport. \n   \nNatural gas provides around 20% of the world's consumption of energy, and as well as being burnt in power stations, is used by many people to heat their homes. \nIt is easy to transport along pipes, and gas power stations produce comparatively little pollution.\n\nOther fossil fuels are being investigated, such as bituminous sands and oil shale. The difficulty is that they need expensive processing before we can use them; however Canada has large reserves of 'tar sands' , which makes it economic for them to produce a great deal of energy this way. \nFind out more at www.eia.doe.gov/emeu/cabs/canada.html \n\nThe steam that has passed through the power station's turbines has to be cooled, to condense it back into water before it can be pumped round again. This is what happens in the huge "cooling towers" seen at power stations. \n\nSome power stations are built on the coast, so they can use sea water to cool the steam instead. However, this warms the sea and can affect the environment, although the fish seem to like it. \n \nAdvantages\nVery large amounts of electricity can be generated in one place using coal, fairly cheaply. \n\n\nTransporting oil and gas to the power stations is easy. \n\n\nGas-fired power stations are very efficient. \n\nA fossil-fuelled power station can be built almost anywhere, so long as you can get large quantities of fuel to it. Didcot power station, in Oxfordshire, has a dedicated rail link to supply the coal. \n\nDisadvantages\nBasically, the main drawback of fossil fuels is pollution. \nBurning any fossil fuel produces carbon dioxide, which contributes to the "greenhouse effect", warming the Earth. \n\nBurning coal produces more carbon dioxide than burning oil or gas. It also produces sulphur dioxide, a gas that contributes to acid rain. We can reduce this before releasing the waste gases into the atmosphere.\n\nMining coal can be difficult and dangerous. Strip mining destroys large areas of the landscape.\n\nCoal-fired power stations need huge amounts of fuel, which means train-loads of coal almost constantly. In order to cope with changing demands for power, the station needs reserves. \nThis means covering a large area of countryside next to the power station with piles of coal.

One example is Photosynthesis, an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. \n\nThis reaction requires a tremendous amount of energy, 572 kJ to be exact. \n\n\n2H2 + O2 = 2H2O + ENERGY\nThis is also an example of an exothermic reaction, a reaction that produces energy. It is also an example of what is called a combustion reaction, where a substance (in this case hydrogen gas) is combined with oxygen. You are probably familiar with this reaction through two tragic examples of the unleashed energy of the combustion reaction of hydrogen, the Hindenburg, and the spaceshuttle Challenger. \n\n\n\n\nCan we create Hydrogen from Water?\nOh Yes! It's the same chemical reaction, but run in reverse: \n\n2H2O + ENERGY = 2H2 + O2 \nNotice now that the requirement is for energy to be ADDED TO the reactants. This is an example of an Endothermic reaction. This means that we could use Water as a Fuel! IF (and this is a big if) we could find an easy way to convert the water to hydrogen and oxygen, then the hydrogen could be used as a clean fuel.\n\nOne way to convert Water to Hydrogen and Oxygen is through the process of Electrolysis - using electricity as the source of energy to drive the reaction.

I would start with the sun. It is the source of all the energy we get. It made the plant grow that the dinosaurs ate that we get fossil fuel from. It causes the weather that we can get wind energy or tidal energy, or we can get solar power directly. Yup.. start with the sun and trace every kind of energy you can think of back to it.

when plants and animals died millions of years ago, they decayed into a variety of substances. they got buried in the earth, and over time, heat and pressure reaaranged the molecules. both plants and fossil fuels are made primarily of carbon and hydrogen.

All fossil fuels are formed by decayed plants and animals. Oil, gas, coal.

Coal is actually the world's most plentiful fossil fuel, but it is alos the dirtiest.  \n\nIt is non-renewable.  \n\nCoal mining is difficult and dangerous.  All over the world hundreds of coal miners die every year because of the hazards of mining it.\n\nBurning coal produces emissions of sulphur dioxide, nitrogen oxides, and carbon dioxide which contribute ot acid rain and global warming.\n\nStrip mining, while safer for the miners, destroys large ares of landscape.\n\nCoal fired power stations need huge amounts of fuel, whihc means covering large areas of countryside close to the power station with piles of coal.\n\nI have attached some websites that should give more information.  I hope this helps.
