Starter: What happens during burning? Set light to a small amount of ethanol in a watchglass or light a small candle. Students should think of three key ideas that explain the burning: fuel, reaction with oxygen from the air and reduction in size of the candle as it burns have been covered. Exploring: Fuels used in vehicles Students research the wide range of fuels used to power vehicles, e.g. external combustion engines that burn fuels to produce steam, as well as internal combustion engines that burn the fuel within the engine. Explaining: Internal and external combustion engines Extend this to consider the impact of type of engine on size and to help explain why cars use internal rather than external combustion engines.
