Energizer Lab - A Target Inquiry Activity
// Wednesday, October 10, 2012 • Deanna Cullen
I was lucky enough to be part of the second cohort of Target Inquiry teachers at Grand Valley State University. As part of the program, we each wrote, tested and revised two chemistry laboratories for use at the high school level. One of mine is the lab I am sharing here.
