Class 5 have been working on the topic of 'rocks and soils'. We began by exploring different types of rock and classifying them according to their characteristics. We then explored how rocks are formed and used drama to help us remember the different ways. Then the children conducted an experiment and made their own volcanic explosion using vinegar and bicarbonate of soda. The topic proved very popluar with the children, and they brought rocks and books in from home to explore.
