Miss Smith's Science classes created some excellent chemical reaction posters detailing the stages of combustion, see below for examples of fantastic project work and home learning!
'Fire comes from a chemical reaction between oxygen (in the atmosphere) and some sort of fuel like wood or maybe even gasoline'
'A chemical reaction might involve the temperature changing. Making a noise or turning into bubbles, liquid, gas, solid, going a different colour or having a PH change.'
'To test for hydrogen you have to do the sqeaky-pop test. This is when you put a metal in acid and close the lid, wait a few seconds then take the lid off and put a flame through the top. If it pops, then you have made Hydrogen.
'Metal ions burn with different colours, flame tests can be used to detect which metals are in a solution. These ions are also used in fireworks to make the different colours'
