This mini demonstration allows a few students to get up and moving to test why we cannot accurately measure temperature with our skin! This can be done to introduce thermometers and other technologies. This can also be done as a lab experiment for the entire class.
This lab allows students to see the effects that heat has on the speed of the chemical reactions (and the speed of the liquid particles) in a glow stick. The speed of the particles in the glow stick ultimately affects the brightness of a glow stick!
