Working on demonstrations that were considered useful and graphic teaching tools received considerable energy from the participants at the North West Workshop for Teachers of Chemistry (NWW) under the direction of Dr. Glenn Crosby at Washington State University in 1987. Some new demonstrations were developed, but most of the effort was spent dealing with traditional and published successful teaching aids to make the directions uniform and clear, even to teachers without extensive chemistry training, and to perfect directions that would work every time.
