Rock layers

Today we did a hands on demonstration modeling the layers of rocks in the Earth.  We connected these layers in small cups in the room to layers that people travel far and wide to see.  To do this we visited a website, Gigapan which has super high resolution pictures that you can amazingly zoom into and pan across.

We also passed around a jar of ash from the eruption of Mt. St. Helens.  Here is some more information about this dramatic even in US Geological history:
