Chocolate Rocks

Today the year 3 children have been learning all about rocks and how they are formed. We have used 3 different types of chocolate to help us make some chocolate rocks.

The children layered together dark, white and milk chocolate and applied pressure to form a sedimentary rock. The chocolate was then heated in the children's hands so the layers merged together to form a metamorphic rock. The layers were now mixed in and unclear to see. Mrs Ashford-Eaton and Miss Young then put their chocolate into boiling water and it melted. We then took it out and let it solidify again to form an igneous rock.
