They Quipped, Saying that my Rhapsodic Petrology Professor "has Rocks in His Head"! Now Those Rocks are in My Head!, October 2011

These spiral bound writings were an ongoing effort by Dr. Poppensiek to continue to educate and inform youth and adults alike. The topics are mainly science related and were inspired by his own ideas of knowledge that he thought was important or by subjects and concepts that were relevant to what people close to him were currently learning about in school. While each item is themed they often cover a wide range of topics within a single volume. They contain many color graphics and photos and some contain cover letters placed inside.
