KS3 Chemistry F4 - Firefighting Form Group 1G 16th January 2007

Starter Activity... F4 - Firefighting Burning is the scientific word for combustion The reactants of combustion are the fuel and oxygen Burning is a chemical reaction. True or False? False True True

The air... Nitrogen oxygen Carbon dioxide Other gases F4 - Firefighting

Investigation work Candle in a jar How different sized jars affect how long it takes for a candle to go out? F4 - Firefighting

Fire Triangle

Class Notes... 1 – 1 – Combustion or burning is a chemical reaction that uses up oxygen and fuel. 2 – 2 – The three ways of putting out a fire are: -Remove the fuel. -Remove the oxygen. -Cool it down so there is enough energy to start the next bit of fuel burning. F4 - Firefighting
