This year’s National Chemistry Week (NCW) crime-based theme of “Solving Mysteries Through Chemistry” captured everyone’s interest! Our ChemClub is part of Prince of Peace, a K through 12 Catholic school on the Mississippi River, in Clinton, Iowa. With all grades located in the same building, the elementary students were able to come to the science lab for NCW. It was a chance for them to wear goggles and be crime detectives. They did tests with fiber, fingerprints, and blood. My students discovered that they like teaching!
