Acid & Base Theories, Concentration | High School
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
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.

Lab: The Egg-straordinary Issue
In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.
-
Titrations, Indicators, Molarity, Concentration | High School
Demonstration: How to Perform a Titration
In this demonstration, the teacher will show how a titration is set-up and performed. Also, the teacher will utilize different indicators to show how they work and why they are necessary. At the end of the demonstration, the teacher will also explain how to calculate the molarity of the unknown substance.

-
Acid Base Reactions, Stoichiometry, Limiting Reactant | High School
Lab: Fizzy Drink
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
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.

Chemical Change, Chemical Change, Observations, Acid Base Reactions, Chemical Change, Acid | Elementary School
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.
