Middle School Chemistry: Changing State: Evaporation
Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.
American Chemical Society
Middle School Chemistry: Temperature and Density
Observe how heating and cooling affect the density of water. Combine the concepts of temperature, molecular motion, and density to learn that hot water is less dense than room temperature water and that cold water is more dense.

Middle School Chemistry: Lesson Plans: Temperature Changes in Dissolving
Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...
American Chemical Society
Middle School Chemistry: Molecules in Motion
Students observe, on a molecular level, how heating and cooling affect molecular motion.
