Learning and caring together, building a firm foundation for the future

Choc Rocks

This week during science we have been looking at the three different types of rock. We used chocolate and other tasty treats to discover how each rock type is made.

Igneous Rocks

This rock is made when hot magma (melted chocolate) erupts out of the centre of the earth, causing magma to spill down the sides of the volcano (chopping boards). Soon the Magma solidifies and forms Igneous rocks.

    

 

Sedimentary rocks

When tiny particles of Rock (chocolate), plants (rice crispy treats), and other organic mather (marsh mellows) are combined and compressed over millions of years.

   

Metamorphic rock

Sedimentary (white chocolate) and igneous rocks (milk chocolate) become subject to tremendous heat and/or pressure over a long period of time , this causes them  to change into a metamorphic rock.

   

 

We had lots of fun learning about and creating the different types of rocks.
