Establishing Equilibrium, Equilibrium Constants, Le Châtelier's Principle, Reaction Quotient  High School
Lesson Plan: Equilibrium Unit Plan Mark as Favorite (4 Favorites)
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 equilibrium to your students.

Equilibrium Constants, Reaction Quotient, Le Châtelier's Principle  High School
Lesson Plan: Q, K, and Le Chatelier Mark as Favorite (6 Favorites)
In this lesson students practice applying Q vs K as an explanatory tool in a simulation and demonstration. In both activities, students will consider how a change in concentration of one species subsequently effects all the species as equilibrium is reestablished.

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 Mark as Favorite (11 Favorites)
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.

Equilibrium Constants, Le Châtelier's Principle  High School
Activity: Equilibrium in a Beaker Mark as Favorite (20 Favorites)
In this activity, students will model equilibrium reactions using plastic chips to represent atoms. The goal of the lesson is to connect the symbolic model of an equilibrium reaction to its particle model.

Reaction Rate, Activation Energy, Hess's Law, Exothermic & Endothermic, Le Châtelier's Principle  High School
Lab: Kinetics and Equilibrium Mark as Favorite (5 Favorites)
In this lab, students will investigate the reaction of the hydrogen sulfite ion (HSO3) and the iodate ion (IO3) to determine the effect that changing concentration and temperature has on the reaction rate.

Establishing Equilibrium, Le Châtelier's Principle, Equilibrium Constants, Reaction Quotient  High School
Lesson Plan: Discovering Equilibrium Mark as Favorite (14 Favorites)
In this lesson students manipulate sets of given conditions to discover what equilibrium is, and how the equilibrium is established from different starting conditions. Students then refer back to the activity as the foundation framework for the rest of Essential Knowledge 6.A, 6.B.1 and 6.B.2. This lesson focuses on both a qualitative and quantitative understanding of equilibrium.

Establishing Equilibrium, Le Châtelier's Principle  High School
Activity: Simulation Activity: Predicting Shifts in Equilibrium: Q vs K Mark as Favorite (10 Favorites)
In this simulation, students will take a 15 question quiz. Each quiz questions has two parts. The first part requires the student to calculate the value of the reaction quotient, Q. In the second portion of the question, the students will compare the value of Q to the equilibrium constant, K, and predict which way the reaction will shift to reach equilibrium. The simulation includes five different reactions which each have three scenarios: Q > K, Q = K, and Q < K.

Establishing Equilibrium  High School
Activity: Equilibrium Introduction Mark as Favorite (11 Favorites)
In this activity, students perform a handson activity that models chemical equilibrium based on the article Equilibrium: A Teaching/Learning Activity by Audrey H. Wilson from the Journal of Chemical Education, Vol. 75, No. 9, September 1998.

Le Châtelier's Principle, Reversible Reactions, Concentration  High School
Lab: Le Chatelier’s Soda Mark as Favorite (31 Favorites)
In this lab, students will observe how the equilibrium of a chemical reaction is affected when a change in pressure, temperature, and concentration is applied to the system.

Establishing Equilibrium  High School
Animation: Equilibrium Animation Mark as Favorite (8 Favorites)
In this animation, students will visualize equilibrium with the help of water and a piece of chalk (calcium carbonate). **This video has no audio**

Le Châtelier's Principle, Establishing Equilibrium, Equilibrium Constants  High School
Demonstration: Le Châtelier’s Principle Mark as Favorite (6 Favorites)
In this demonstration, students will witness a system at equilibrium and apply different stresses to see how the equilibrium shifts.

Activation Energy, Temperature, Exothermic & Endothermic, Heat, Equilibrium Constants, Establishing Equilibrium, Le Châtelier's Principle, Reaction Quotient  High School
Activity: Reversible Reactions Simulation Mark as Favorite (6 Favorites)
In this activity, students will investigate how temperature, activation energy, initial amounts of products and reactants, and type of reaction (exo or endothermic) effect the equilibrium position of a reaction using a simulation.

Indicators, Le Châtelier's Principle  High School
Demonstration: Milk of Magnesia Magic Mark as Favorite (19 Favorites)
In this demonstration, students will observe a color change in a milk of magnesia solution as vinegar is added.

Le Châtelier's Principle, Establishing Equilibrium, Reversible Reactions, Reaction Rate  High School
Lab: Dynamic Equilibrium Simulation Mark as Favorite (10 Favorites)
In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.
