  • Acid & Base Theories, Concentration | High School

    Access is an AACT member benefit. Lesson Plan: Calculating pH, A Look at Logarithms

    In this lesson, students will be introduced to a base-10 logarithmic scale and use it to calculate pH from hydrogen ion concentration. Often students are able to calculate pH by pushing the correct buttons on their calculators, but they don’t understand what the values mean. This lesson attempts to bridge that gap using a guided inquiry model.

  • Buffers, Acid & Base Theories | High School

    Lesson Plan: Preparation and Evaluation of Buffers

    In this lesson students will use multiple methods to calculate and prepare buffered solutions with a desired pH. Upon preparation of the solutions, the students will explore differing aspects of buffers including buffering capacity and predominant form.

  • Salts, Equilibrium Constants, Strong vs Weak | High School

    Access is an AACT member benefit. Lesson Plan: Categorizing, Calculating and Applying Concepts from Weak Acids, Weak Bases and Salts

    In this lesson students will write dissociation reactions to make connections between conjugate acid-base pairs. They will use beaker diagrams in a cooperative group activity to better understand why the pH calculation for a weak acid/base is not the same for a strong acid/base. Finally, students will apply these concepts in a lab in which they will identify several unknown, clear, colorless solutions using factors such as pH, conductivity and reactivity. The activities in this lesson can be used in sequence or as standalone activities.

    In this lab, students will learn the properties of acid and bases while applying the principles of stoichiometry to calculate the amount of base needed to neutralize an acid completely and produce a bubbly drink.

  • Buffers | High School

    Access is an AACT member benefit. Activity: What are Buffers?

    In this activity, students will complete a card sort that will allow them to understand what makes up a buffer solution and how it works to keep pH from changing.

    Access is an AACT member benefit. Lesson Plan: The Chemistry of Eggs

    In this lesson students will learn that vinegar can react with the Calcium in an egg shell to make it rubbery. First, the students will listen to the teacher read a book about eggs. The teacher will then put an egg in a jar with vinegar and let it set for two days. Students will make a prediction about what they think will happen to the egg, and then together they will investigate the final results.
