Irreversible changes


Year 5 have been investigating irreversible changes. They conducted various independent experiments to observe the reactions made when materials are heated or mixed together. Using their observational skills, they came up with their own conclusions about what defines an irreversible change. Pupils independently cracked eggs and mixed them up, observed and recorded information about what happens to lit candles and our favourite was making 'Angel Delight'.


"I enjoyed thinking about which experiments we could do to observe irreversible changes." - Darren 


"The Angel Delight was my favourite because it smelled yummy!" Scarlett
