Carolina Investigations® for AP® Chemistry: Le Châtelier's Principle and Equilibrium Shifts Kit

Item # 840594 Exclusive

Addresses AP® Chemistry Big Idea 6 and Learning Objective 6.9. Investigate how temperature, concentration, and pressure affect chemical equilibrium in 3 different reactions. This experiment addresses equilibrium changes both in solution and in the gas phase, shows the reversible nature of reactions, and provides visual interest by using changes in color to monitor chemical reactions. It also includes a discussion of the Haber process. For 30 students working in teams of 3.

  • Aligned with Big Idea 6 and Learning Objective 6.9
  • Emphasizes Science Practices 3, 4, 5, 6, and 7

Investigate how temperature, concentration, and pressure affect chemical equilibrium in 3 different reactions. Teach this laboratory experience using either the guided activity or inquiry activity. In the guided activity, students perform 3 separate activities to investigate chemical equilibrium. In the first investigation, they react starch and iodine at 3 different temperatures and observe the variation in color. In the second, they react magnesium hydroxide with an acid to determine the affect a change in hydroxide-ion concentration has on solubility. For the third investigation, they pull a partial vacuum on carbonated water to show how pressure changes affect pH. Students also observe how changes in temperature and common ions affect the equilibrium between 2 complex ions. In the inquiry activity, students design experiments to show how temperature, concentration, and pressure affect the equilibria of starch-iodine, magnesium hydroxide, and carbonated water. They also design an experiment to maximize the percent yield of a reaction by adjusting temperature and reactant concentration.

Both activities include Big Idea assessment questions that follow the format of the AP® Chemistry Exam free-response questions. In the Big Idea assessment, students consider how stresses applied to the reactions of photosynthesis and the buffering of blood would affect their equilibria, and how to maximize the formation of either reactants or products using these stresses.

Provides the following AP® Chemistry experiences: design a procedure to collect data, analyze data, make observations, construct explanations of phenomena based on evidence and make predictions about natural phenomena. This experiment addresses equilibrium changes both in solution and in the gas phase, shows the reversible nature of reactions and provides visual interest by using changes in color to monitor chemical reactions. It also includes a discussion of the Haber process. Materials are sufficient for 30 students in teams of 3. Digital teacher’s manual, included FREE with kit purchase, is a 12-month eBook license to the Le Châtelier’s Principle and Equilibrium Shifts teacher’s manual. You can also access the digital student guide for this kit for free at Carolina Science Online®.

Carolina Investigations® for AP® Chemistry: Kits That Support the AP® Curriculum

Carolina Investigations® for AP* Chemistry Kits

If you are an AP® teacher, you go out of your way to help your students perform successfully on the AP® Exam. Carolina Investigations® for AP® Chemistry Kits are specifically designed to help you do just that.

Carolina Investigations® for AP® Chemistry kits are specifically designed to meet the goals of the revised AP® Chemistry curriculum. That curriculum and our kit series center on 6 overarching BIG ideas, which provide the themes for an enhanced laboratory experience focused on inquiry-based, student-directed learning:

  • Big Idea 1: Atoms
  • Big Idea 2: Chemical and Physical Properties
  • Big Idea 3: Changes in Matter
  • Big Idea 4: Rates of Chemical Reactions
  • Big Idea 5: Thermodynamics
  • Big Idea 6: Chemical Equilibrium

The AP® Chemistry curriculum emphasizes science practices, which allow students to use the tools of scientists to discover, test, and explain natural phenomena. The science practices of AP® Chemistry are integrated into each lab in the Carolina Investigations® for AP® Chemistry series.

  • Science Practice 1: Modeling
  • Science Practice 2: Math
  • Science Practice 3: Scientific Questioning
  • Science Practice 4: Data Collection
  • Science Practice 5: Data Analysis
  • Science Practice 6: Using Scientific Explanations and Theories
  • Science Practice 7: Connecting Concepts

All Carolina Investigations® for AP® Chemistry kits offer:

  • Two teaching approaches: a guided activity and an inquiry activity
  • Big Idea assessment questions modeled on the AP® Chemistry Exam’s free-response questions
  • Detailed inquiry activity preparation and procedure steps
  • Inquiry activity experimental design template based on the scientific method
  • Inquiry activity grading rubric

Carolina Investigations® for AP® Chemistry kits are designed to help AP® teachers help their students achieve exceptional results by:

  • Facilitating the successful integration of inquiry-based learning into the laboratory experience
  • Using teacher-developed and field-tested activities that are designed for the AP® classroom
  • Cultivating students’ conceptual understanding of the topics covered, while allowing them to draw upon real-world connections
  • Mirroring the free-response section of the AP® Exam using assessment questions focused on the Big Ideas
  • Integrating mathematics and analytical thinking through the graphing and interpretation of student-collected data
  • Reinforcing knowledge by connecting concepts to students’ lives
  • Minimizing teacher prep and cleanup time
