1 – 10 of 10 Classroom Resources

• Equilibrium Constants, Le Châtelier's Principle | High School

Access is an AACT member benefit. Activity: How do Pollutants Affect our Oceans?

In this activity, students will use the simulation, Surface Ocean pH Levels, from the Chemistry in Context Simulation Suite to investigate the values related to ocean acidification and interpret systems with multiple equilibria.

• Establishing Equilibrium, Equilibrium Constants, Reaction Quotient, Graphing | High School

Access is an AACT member benefit. Activity: Shaking Dice to Model Equilibrium Principles

In this activity, students work together in small groups using a variety of multi-sided dice to model the dynamic character of a chemical equilibrium. Students will collect, share and analyze data in order to understand that the rate of a chemical reaction depends on the concentration of reactants (and products) as modelled by the different sided dice.

• Le Châtelier's Principle, Equilibrium Constants, Establishing Equilibrium, Reaction Quotient | High School

Access is an AACT member benefit. Activity: Le Châtelier's Principle Particulate View

In this activity, students will gain a better understanding of how applying a stress to a reaction system will shift the equilibrium. The students will be able to predict the direction a reversible reaction will shift based of the value of the reaction quotient (Q) and the equilibrium constant (K). This activity should be completed after students have completed the activity “Equilibrium Particulate View.”

• Establishing Equilibrium, Equilibrium Constants, Reaction Quotient | High School

Access is an AACT member benefit. Activity: Equilibrium Particulate View

In this activity, students will gain a better understanding of what it means for a reaction to be in a state of equilibrium and how a reaction progresses over time to establish equilibrium. Students will also relate the equilibrium constant to the amount of products and reactants present at equilibrium.

• Equilibrium Constants, Le Châtelier's Principle, Reaction Quotient | High School

Access is an AACT member benefit. Activity: Equilibrium in a Beaker

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.

• Establishing Equilibrium, Le Châtelier's Principle | High School

Simulation: Predicting Shifts in Equilibrium: Q vs K

In this simulation, students will take a 15 question quiz. Each quiz question 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

Access is an AACT member benefit. Activity: Equilibrium Introduction

In this activity, students perform a hands-on 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.

• Establishing Equilibrium | High School

Access is an AACT member benefit. Animation: Equilibrium Animation

In this animation, students will visualize equilibrium with the help of water and a piece of chalk (calcium carbonate). **This video has no audio**

• Activation Energy, Temperature, Exothermic & Endothermic, Heat, Equilibrium Constants, Establishing Equilibrium, Le Châtelier's Principle, Reaction Quotient | High School

Access is an AACT member benefit. Activity: Reversible Reactions Simulation

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.
