Woodpeckers learned all about reversible and irreversible changes. They watched a video of paper burning and the children were fascinated that it ‘disappeared’, and through watching, learned that this was an example of an irreversible change.
In the cooking room, the class cooked some rice, pasta and toast, comparing each before and after to note their changes. We also made predictions, which the children learned was giving ‘a good guess’, about what would happen to brown sugar if put into water.
The children’s predictions were brilliant, saying that the sugar would ‘melt’ and change the colour of the water. They also discussed that whilst ice can melt if left in the sun, if placed back in the freezer, it would once again turn to ice and this is an example of a reversible change. Woodpeckers really enjoyed learning about reversible and irreversible changes, and it was wonderful to hear them using scientific language correctly.
