I think the idea is basically sound, but I worry that students don't connect the BB curve to light intensities or to temperatures conceptually, so that in effect they are just playing with a graph.
In addition, I would make some use of the colored star feature to help students connect to the idea
of color and temperature. Finally, you say in a few spots that the BB curve is a Gaussian, it's not.
