Curated OER
Exothermic and Endothermic Reactions
Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity,...
Curated OER
Energetic Energy: A Child?s Guide to Responsible Energy Use
Students explore how energy transforms into heat. In this energy instructional activity students create models and find a need for fuel to make a Stirling engine.
Curated OER
Heat Unit
Students define thermal equilibrium. They distinguish between internal energy and heat. Students describe how the quantity of heat that enters or leaves a substance is measured.
Curated OER
Entropy
In this entropy worksheet, students calculate the change in entropy and rank absolute molar entropies. This worksheet has 12 problems to solve.
