This might just seem like a drab picture of a rock, but to those who teach science, this is a gem. A folded metamorphic rock bent and twisted by the heat and pressure of the earth over thousands of years. Add in the thousands of years it would then take for this rock to reach the surface and you can understand how rare it is to stumble upon one of these.
I could use this image in many ways for science. It has obvious signs that it is a metamorphic rock. I could show this in class and ask students to explain how this was formed, or prove to me the type of rock it is. For the creative students, I could ask them to tell the story of the rock through the rock's point of view. Any of these assignments would let me know if the students can apply their geology knowledge to identify the rock.

Here is a link to my own photo of a metamorphic rock at the end of my neighbor's driveway. It has a similar story, only it was probably pushed hundreds or thousands of miles by glaciers.

  1. The life of a rock... makes for such neat stories. This is definitely a great photo. You also need one from the Creative Commons site.
