My high school in Chattanooga had a single small science lab that served for general science, chemistry and physics. It was not well equipped, but it did have prominently displayed on the wall one of those big colorful Periodic Tables of the Elements that Sargent-Welch used to sell, and may still do for all I know. I sat right beside the chart and spent a lot of time looking at it. See this week's Musing.
