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.
