Pupils investigate which materials will return to their original state when heated and then cooled. They make predictions then carry out an investigation.
Learning Objectives:
PoS - explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible, including changes associated with burning
NaG - pupils should explore changes that are difficult to reverse, such as burning
WS - pupils could observe and compare the changes that take place, for example when burning different materials
