Sedimentary, metamorphic or igneous?

First, Zennor Class grated rock to cause sediment or parts of rock.

 

Then, we applied pressure to the rocks; squeezing and pushing the sediment together. This formed our sedimentary rock.

 

After that, we applied more pressure and heat to change the rock’s form to metamorphic rock. We discussed the idea of morphing and changing.

 

Finally, we melted our wax crayons to create igneous rock. We watched the rock cool and change form, once more.
