Useful thermodynamic concepts from the simple coin toss experiment

A guided discovery activity with the help of online available free resources in the form of a simple coin toss experiment focused on active understanding to reveal the important thermodynamic concepts of microstate, macrostate, multiplicity and probability is described in detail here. Materials are readily available everywhere: a bunch of coins suffices in the most basic version. We suggest several alternatives ranging from elementary demonstrations to elaborate statistical analysis, thus the experiment may be carried out to any degree of sophistication, from high school to advanced college levels.
