Properties of Fresh and Sea Water
Middle schoolers work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
Temperature Change and the States of Matter
Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.
