Changing state machines
Year 5 topic on Chemistry. Based on what they have learnt, this display comes at the end of the unit. With lots of visual stimulous, they have to unse their imagination to change water back and forth between solid, liquid and gas. They can be very creative and throw water into a volcano to evaporate, slice ice up with a laser to increase surface area or send water to the Arctic to freeze it. Also included is sonic vibration (like a sonic toothbrush but much more powerful - available from aquarium stores) which turns water into water vapour.
