Burning
How does it occur, what effects/side-affects does it have on the environment, and how can we reduce the side-affects
How does a candle burn?The clip to the right explains that a candle doesn't burn from just the wick, it is actually a mixture of the wick and gas produced from the candle chemically changing from a solid to liquid.

So how can we use this knowledge to understand the effects that cars have on the environment?
This definition gives a good outline to answer the question above. However when working with children, words specific to the topic will have to be discussed in detail prior to or after reading the statement to ensure students have the ability to fully understand what is being said.
"Vehicle emissions can affect the environment in several ways. Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming. Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals. Nitrogen oxides and sulphur oxides are major contributors to acid rain, which changes the pH of waterways and soils and can harm the organisms that rely on these resources."

Definitions of technical words specific to the topic;
Acid rain - precipitation, as rain, snow, or sleet, containing relatively high concentrations of acid-forming chemicals, as the pollutants from coal smoke, chemical manufacturing, and smelting that have been released into the atmosphere and combined with water vapour: harmful to the environment.
Carbon dioxide –a colourless, odourless, incombustible gas, CO2, present in the atmosphere and formed during respiration, usually obtained from coal, coke, or natural gas by combustion, from carbohydrates by fermentation, by reaction of acid with limestone or other carbonates, or naturally from springs: used extensively in industry as dry ice, or carbon dioxide snow, in carbonated beverages, fire extinguishers, etc.
Emission – a) An act or instance of emitting: the emission of poisonous fumes.
b) Something that is emitted; discharge; emanation.
Emit –To send forth (liquid, light, heat, sound, particles, etc.); discharge.
Global warming – An increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.
Greenhouse gasses – any of the gases whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, ozone, and the fluoro-carbons.
Sulphur oxides – any of several compounds of sulphur and oxygen, the most important of which are sulphur dioxide (SO2) and sulphur trioxide (SO3), both of which are manufactured in huge quantities in intermediate steps of sulphuric acid manufacture. The dioxide is the acid anhydride (a compound that combines with water to form an acid) of sulphurous acid; the trioxide is the acid an hydride of sulphuric acid.
