==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===
===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.

When a [[chemical]] burns in the presence of [[oxygen]].
