Equilibrium Constants, Le Châtelier's Principle, Gibb's Free Energy , Enthalpy, Entropy, Solubility  High School
Lesson Plan: Relationship Between Free Energy and the Equilibrium Constant
In this lesson, students will explore the relationships between solubility and Keq (specifically Ksp), as well as Keq and ΔG°. First, a guided inquiry activity will introduce the relationship between standard free energy and equilibrium constant with the equation ΔG° = RTlnKeq. Then data collection regarding solubility of potassium nitrate at various temperatures will lead to the calculation of Ksp and ΔGo for the dissolution reaction at those temperatures. Students will manipulate the equations ΔG° = RTlnKeq and ΔG° = ΔH°  TΔS° to derive a linear relationship between 1/T and lnKeq, which will then be graphed to determine values for ΔH° and ΔS°.

Enthalpy, Entropy, Gibb's Free Energy  High School
Lab: Thermodynamics Escape Room
In this lab, students are presented with an escape room scenario that challenges them to complete three tasks in order to escape from an old, mysterious Gothic house. Students are given access to a small assortment of chemicals, and standard lab equipment. They must determine which chemicals and equipment will help them to light a tap light without touching it, free a key from a block of ice without using a conventional heat source, and free a lock that is buried in a pile of glue.

Enthalpy, Entropy, Gibb's Free Energy , Spontaneous vs. Nonspontaneous Reactions, Exothermic & Endothermic  High School
Lab: Investigating Enthalpy and Entropy
In this lab, students will be able to observe and measure energy changes during the formation of solutions. The students should be able to explain and describe these changes in terms of entropy, enthalpy and free energy.

Heat, Temperature, Specific Heat, Exothermic & Endothermic, Energy Diagrams, Hess's Law, Calorimetry, Entropy, Enthalpy, Gibb's Free Energy  High School
Lesson Plan: Thermochemistry and Thermodynamics Unit Plan
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. We constructed a unit plan using AACT resources that is designed to teach thermochemistry and thermodynamics to your students.

Equilibrium Constants, Reaction Quotient, Activation Energy, Energy Diagrams, Catalysts, Enthalpy, Entropy, Spontaneous vs. Nonspontaneous Reactions  High School
Lesson Plan: Making Connections in Kinetics, Equilibrium and Thermochemistry
In this lesson students will understand the connections between the equilibrium constant (K) and the reaction quotient (Q) as well as how they determine the favorability of a reaction. Additionally students will be able to determine if a reaction is kinetically favored or thermodynamically favored.

Entropy, Gibb's Free Energy , Enthalpy  High School
Lesson Plan: Enthalpy and Entropy as Driving Forces
In this activity, students observe various chemical and physical processes to qualitatively predict and explain the signs of ∆S and ∆H. Based on their observations, they will predict the sign of ∆G and will determine the driving force of the process. Students will then calculate ∆S, ∆H and ∆G. This lesson focuses on thermochemical predictions, calculations and explanations.

Entropy  High School
Activity: Entropy
In this activity, students will define entropy and be able to recognize entropy changes in chemical reactions.

Entropy, Kinetic Molecular Theory, Molecular Motion, Intermolecular Forces, Density, Volume  High School
Activity: Connecting States to Entropy
In this activity, students use blocks to model different states of matter and the Kinetic Molecular Theory to understand the concept of entropy. This is a concept mandated by SAT level or AP level high school chemistry class.
