Science in Year 5

18th December 2019

Science

5HH have been looking at reversible and irreversible reactions. This culminated in an unusual ‘triple lesson’ last week, during which 4 investigations were completed to see if different reactions could be reversed or not. After the investigations, they witnessed a sugar snake and saw the coloured flame and huge snake that erupted, using the heat as a catalyst. They finished the session by making vinegar rockets using vinegar and bicarbonate of soda. Despite being a 105 minute lesson all the pupils were fantastically behaved and sensible using flames and fully engaged in the topic.
