What’s under our feet?

In science Class 3 have been learning about rocks and soil.  We began by asking the question 'What is under our feet?'   After lots of discussion, and some very interesting theories, Class 3 drew some fantastic diagrams to illustrate the internal structure of the Earth from the topsoil all the way to the inner core. 

In another lesson we learned about the three main types of rock: igneas, sedimentary and metamorphic.  The class then made their own 'sedimentary rock' using grated chocolate to illustrate the separate layers.
