Types of Rocks

We found out about how different types of rocks are formed. We made igneous fudge to show how igneous rocks are formed. Igneous rock is made by lava (molten rock) cooling down and becoming solid. 

Before the "rock" is heated:

Hot bubbling lava!

Metamorphic rocks are made from different types of rocks which are heated and put under enormous pressure to form a new rock. We showed this by making "Metamorphic Munchies"!

The finished Igneous Fudge and Metamorphic Munchies.

The third type of rock is called sedimentary rock. This is formed by layers of sediment settling at the bottom of rivers and streams. Over millions of years this becomes compacted and solid. Luckily it didn't take us that long to make our Sedimentary Sandwiches!
