How to identify a physical change from a chemical change
Learners 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.

Heat Loss and Gain in Physical Changes and Chemical Reactions
Students measure the heat of physical and chemical changes in reactions. In this chemistry lesson students determine at what extent changes emit or absorb heat.
Curated OER
Classification of Changes
In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...
