Chris is an elementary principal and former science supervisor.  He is currently a district director for NSTA.  He shares a lesson involving a rock from Antartica, a reading a passage about properties, and calling the most important person in the world (his mom!). He discusses the importance of teachers being willing to try new things and helping students learn to have civil conversations about science issues.  He also tells us about one of his proudest moments of having a former student collaborate with current students about local entomology research.
