Year 4 Science

Year 4 came together this afternoon and learnt about reversible and irreversible changes.  They looked at butter, cheese, chocolate, candle wax, egg and a stone in cups floating in hot water.  The children made observations afterwards in cold water to see which materials were reversible.

Predictions were made and the overall conclusion was that: stone didn't change and all the others were reversible except for the egg.  Discussions about cheese were had related to cooking.  Great scientists at work!!
