Making rocks


In year 3 and 4 we have began our topic on Rocks. We have learnt about the types of rocks and how they are made. 

  • Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans.

  • Igneous rock is formed when magma cools and solidifies, it may do this above or below the Earth's surface.

  • Metamorphic rocks can be formed by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

 

We then used chocolate to create our own rocks. With the help of Mrs Ryder and Mrs Wright we used chocolate to form each rock type. The children did an outstanding job and we created some brilliant rocks!
