The rock cycle

Today we learnt about the three different types of rock: sedimentary, igneous and metamorphic. We did this by creating out own chocolate rocks with different kinds of chocolate. First, we made a sedimentary rock by compressing the chocolate chips so they were stuck together and formed layers. Next, we made a metamorphic rock by applying heat and pressure to it with our hands. We then create an igneous rock by putting the metamorphic rock in hot water where it melted into magma and cooled into igneous rock.
