This week, Year 5 explored the fascinating chemical reaction and irreversible change that occurs when vinegar is mixed with bicarbonate of soda. During their experiments, the children observed how the mixture produced a gas, resulting in bubbling and fizzing as carbon dioxide was released. They noted that the original substances could not be recovered, making this a clear example of an irreversible change. After conducting the experiment, the children wrote detailed reports, describing their observations, the chemical reaction involved, and why this reaction cannot be reversed. It was an exciting hands-on lesson in science, reinforcing the concept of irreversible changes in a fun and engaging way.
