Right now we are learning about the 3 phases of matter: solid, liquid, and gas. We are also discussing the affect that heat energy has on the particles of matter in each of these phases.

Today in class we will be conduction an experiment to see what heat does to the movement of particles in a liquid through the Diffusion lab. The outline version of the Diffusion lab is available here:
