Two weeks before the new school year, St. Louis Public School teachers Ninfa Matiase, LaJuana Stidmon and Jeremy Resmann cut red agar into squares before dropping them into vinegar. It’s an experiment to test how quickly the cubes absorb the vinegar — one of several lesson plans the teachers have learned over the past two weeks during training provided by the National Math and Science Initiative.

Stidmon, a science teacher at Clyde C. Miller Career Academy, says the training has given her a framework to focus her AP biology class.
