Over this half term we will begin to dicsover the different types of rocks and how they are formed. We will have the opportunity to comapre and group rocks based on their appearance and simple properties. The children will also learn about how soil is formed, investigating the permeability of different types of soil.

Today we began to explore the different types of rocks and know that there are 3 different types, learning how each are formed.  

  • Igneous rocks are formed when hot magma cools and hardnes. 
  • Sedimentary rocks ar formed when small bits of rocks are transported through rivers to the ocean bed. Over time as more layers pile up and press down on the lower layers. The rock become cemented togther forming a soild layer. 
  • Metamorphic rocks start out as either Igneous or Sedimentary rocks. When the rocks are near hot magma they heat up, which changes the chemicals inside the rock before cooling it down again.
