**Introduction**

"*The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble.*" -- P.A.M. Dirac, 1929

According to the National Science Education Standards [1], “inquiry into authentic questions generated from student experiences is the central strategy for teaching science.” Inquiry involves asking and investigating questions, gathering and analyzing data, and predicting and explaining results.
