Especially JCE: February 2016

The extent of my involvement with football is to check scores to see who won the Super Bowl and to watch an online recap of the best commercials that aired during the game. Nonetheless, I was excited to read, appropriately enough, on Super Bowl Sunday, a football-focused activity in the February 2016 issue of the Journal of Chemical Education.

Stoichiometry is Easy

This article describes a three week lesson plan for teaching stoichiometry using an algorithmic method. Two labs (one designed as a laboratory quiz) several cooperative learning exercises, student worksheets and guided instructional frameworks (forcing students to develop good habits in writing measures and doing problem solving) are included. The highlight of the lessons is the "chemistry carol" (based on Felix Mendelssohn's music for "Hark! The Herald Angels Sing") in which students recite a five-step algorithm for completing stoichiometry problems. 

Seeing Is Not Believing

“It sort of started to look kind of like a very pale blue.” A friend who teaches at the middle school level told me about a science experiment he’d done with his students. The procedure suggested to students that a particular solution would turn blue, but also asked them to write down what they saw happen. The thing was, it wasn’t actually designed to turn blue.
