Ms. Morris's 4th grade class brought their rock knowledge to life Skyping with a geologist. After watching notes and observing rocks on their own, Mr. Bentley, a professor Northern Virginia Community College, answered questions and shared his expertise about rocks.
Mr. Bentley shared that is favorite type of rock is a migmatite; a rock that is partially melted magma and is part of the igneous family. One of the tools in his laboratory is a saw that can grind down rocks to the thickness of a strand of hair. This was an illustration that really fascinated the students as they all began looking or feeling their own hair.
One of the tools that Mr. Bentley uses is a geological map, which shows where rock types are throughout the country and their age. The students were able to successfully complete their K-W-L chart using the information the geologist shared and their own research.
