Fuels and energy

This is a 30 min lesson that could be easily extended to a full lesson with class feedback and other activities linking energy transfer in a real situation. I did 3 demos of fuels so students could see that not all fuels are traditionally though of as fuels. the demos were blowing custard powder/icing sugar into a bunsen, whoosh bottle (big water cooler bottle with a small amount of ethanol and ignite it - it looks like an upside down rocket) and methane bubbles. It really engaged them and they really enjoyed putting ideas about the true or false cards.
