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: Density: Sink and Float for Liquids
Students determine whether a liquid will sink or float in water by comparing its density to the density of water.
American Chemical Society
Middle School Chemistry: Density: Sink and Float for Solids
Students determine whether an object will sink or float by comparing its density to the density of water.

Middle School Chemistry: Changing State: Melting
Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.
American Chemical Society
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...

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: Changing State: Freezing
Students investigate how low temperature causes water vapor to condense into a liquid and then freeze to form a solid.

Middle School Chemistry: Lesson Plans: Can Gases Dissolve in Water?
An activity through which students learn why gas is able to dissolve in water, and how heat affects the solubility of a gas in a liquid.
American Chemical Society
Middle School Chemistry: Molecules Matter
Learners observe and discuss water on the molecular level using the idea that water is composed of tiny molecules that are attracted to one another.
