Willow Petrologists.

Today we became petrologists ( rock scientists ) and looked at different types of rocks, we learnt about;
Igneous rocks - Rocks that are formed when lava cools
Sedimentary rocks - Rocks that are formed over millions of years at the bottom of the sea.
Metamorphic rocks - Igneous or sedimentary rocks that change under high heat or pressure.
We then created a fair test to see if we could work out what different rocks are, we looked at hardness, permeability and did an acid test !
