Today the year 5 scientists created an experiment based on their thinking about reversible and irreversible changes. Although they have just begun this subject, year 5 already had some good ideas about the changes that might occur. They had 4 substances including oil, water, vinegar and bicarbonate of soda and had to devise an experiment to create a reversible or irreversible change. They could choose 2 substances and predict what might happen when they were combined. The pupils then tested out their theory and spoke about the results. Today was about investigating and learning. We will continue to learn from this experiment and do more research and testing to cement our understanding about the changes and explain them.
One group demonstrated their learning to the whole class and as predicted, an exciting irreversible change occurred.
