Lesson: 8-12 class periods, depending on class level. Teacher Preparation: See individual resources. This unit supports students’ understanding of Predict what will happen in terms of thermodynamic favorability if temperature of system is increased or decreased (how the value of Δ G is affected).Relate the significance of the signs of Δ H° and Δ S° to thermodynamic favorability.Given the signs of both Δ H° and Δ S°, determine if a process is thermodynamically favorable, and if that favorability occurs at higher or lower temperatures.Observe a chemical or physical process, and predict the sign of the enthalpy change.Observe a chemical or physical process, and predict the sign of the entropy change.Recognize entropy changes in chemical reactions.Apply Hess’s Law to successfully calculate ΔH rxn of an unknown reaction.Perform a calorimetry experiment to successfully calculate ΔH rxn.Be able to solve problems using Hess’s Law.Interpret data to determine if an endothermic reaction or an exothermic reaction has occurred.Understand how a chemical reaction is related to an energy diagram.Associate an endothermic and exothermic chemical reaction with their related energy diagram.Identify processes as either exothermic or endothermic based on evidence, such as temperature changes in a chemical reaction.Write balanced chemical equations including heat energy.Differentiate between endothermic and exothermic chemical reactions.Define endothermic and exothermic processes.Use the particulate model of matter to explain how kinetic energy is demonstrated amongst the particles of a substance.Explain how perception of hot or cold is related to heat and temperature.

Construct a macroscopic model of how energy is transferred.We constructed a unit plan using AACT resources that is designed to teach thermochemistry and thermodynamics to your students.īy the end of this unit, students should be able to The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations.
