How to identify a physical change from a chemical change
Students identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.

The Effects of Water Quality on the Growth Rate of Freshwater Mussels
Students participate in a field and laboratory study to determine if local freshwater mussels are environmentally stressed.
Curated OER
Gelatin Volcanoes
Learners enjoy a hands on activity to understand how and why magma moves inside volcanoes.
Curated OER
Looking At Acid's Effects On Metals
Students perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.
Curated OER
To Smell or Not to Smell, That is the Ester
Students explain the basic concepts of polymerization. Students participate in a lab to create a crude preparation of carboxyl esterase and test its effectiveness in reducing the residual monomer in an emulsion such as paint.
