==Key Stage 2=====Meaning==='''Burning''' is a chemical reaction that happens when something catches fire. ===About Burning===: Materials can only '''burn''' if there is enough air.: Substances cannot '''burn''' underwater or in empty space.: Anything that '''burns''' is called a [[fuel]]. ===Examples==={| class="wikitable"|-|[[File:SolidBurning.png|center|200px]]|[[File:LiquidBurning.png|center|200px]]|[[File:GasBurning.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |A [[solid]] fuel '''burning'''.| style="height:20px; width:200px; text-align:center;" |A [[liquid]] fuel '''burning'''.| style="height:20px; width:200px; text-align:center;" |A [[gas]] fuel '''burning'''.|}  ===Note to Teachers===Students often don't recognise the difference between heating and burning. When asked what happens to a substance when it is heated they will say 'burn' when melting would be a more appropriate response. Students also do not always recognise the necessity of oxygen (or at least air) when things burn. ==Key Stage 3=====Meaning===[[Combustion]] is an [[exothermic]] [[Chemical Reaction|reaction]] and a type of [[Oxidation]] [[Chemical Reaction|reaction]] that happens when a [[chemicalfuel]] burns in the presence of [[oxygen]]releasing [[Thermal Energy|thermal energy]] and [[light]]. ===About Combustion===: [[Combustion]] always happens at high [[temperature]]s and gives off [[light]].: [[Combustion]] may involve [[Hydrocarbon]]s. This has the general [[Word Equation|equation]]: Fuel + Oxygen → Carbon Dioxide + Water: [[Combustion]] may involve [[Metal]]s. This has the general [[Word Equation|equation]]: Metal + Oxygen → Metal Oxide ===Examples==='''Fuel + Oxygen → Carbon Dioxide + Water''': Methane + Oxygen → Carbon Dioxide + Water: Ethane + Oxygen → Carbon Dioxide + Water: Propane + Oxygen → Carbon Dioxide + Water '''Metal + Oxygen → Metal Oxide''': Magnesium + Oxygen → Magnesium Oxide: Aluminium + Oxygen → Aluminium Oxide: Iron + Oxygen → Iron Oxide {| class="wikitable"|-|[[File:BunsenBurner.png|center|200px]]|[[File:MagnesiumRibbon.png|center|300px]]|-| style="height:20px;
