Description
See the difference between the faster-moving molecules of hot water and the slower-moving molecules of cold water. No scanning-tunneling microscope required. Just baby food jars, hot and cold water, and food coloring dye.

And once the principles of that demonstration are understood, cap it off with a few robust gedanken (thought experiment) questions.
