  • Observations, Chemical Change, pH, Acid Base Reactions, Chemical Change | High School, Middle School

    Lab: How do Sinkholes Form?

    In this lab students will learn how acidic groundwater reacts with limestone, causing it to erode. Sinkholes form when eroded limestone underneath the surface of the earth can no longer support the ground above it. Students will test how acid reacts with a variety of rocks and determine which rocks would be best to build a city on top of in order to reduce the chance of sinkholes forming.

  • History, pH, Acid & Base Theories, Strong vs Weak | High School, Middle School

    Activity: Acid & Base Guys Video Questions

    In this activity, students will watch a video about the history of acids and bases. They will learn about the evolution of these theories, from Lavoisier to Arrhenius, Bronsted-Lowry, and Lewis.

  • pH, Net Ionic Equation, Indicators, Strong vs Weak, Salts | High School

    Lab: Hydrolysis of Salts

    In this lab, students will observe the hydrolysis of several salt samples. They will first predict which solutions are acidic, basic or neutral, and then discover the pH of each through the use of indicators. Students will share and compile their experimental results, as well as have an opportunity to determine the net-ionic equations for each reaction.

  • Concentration, pH, Acid & Base Theories | 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.

  • pH, Acid & Base Theories, Buffers | 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.

  • pH, Strong vs Weak, Equilibrium Constants, Salts | 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.

  • Interdisciplinary, pH, Indicators | High School, Middle School

    Lab: Exhaling Acid

    In this lab students will observe how increased carbon dioxide levels lead to a build-up of acidic conditions.

  • pH, Indicators | High School

    Lab: Exploring the Properties of Acids and Bases

    In this lab, students will rotate through five stations. They will explore the properties of many household substances and discover a few properties of acids and bases.

  • Concentration, pH, Molarity, Titrations, Indicators | 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.

  • Solubility, pH, Molecular Structure, Buffers | High School

    Lab: Aspirin Tablets: Are they all the Same?

    In this lab, students will design an experiment to test the time and completeness of dissolution of various types of aspirin in different pH environments.

  • pH, Ionic Bonding, Net Ionic Equation | High School

    Lab: The pH of Salts

    In this lab, students will determine whether an aqueous solution is acidic, basic, or neutral. Students will write net ionic equations for the hydrolysis of a solution.

  • pH, Indicators | High School, Middle School

    Lab: Cellular Respiration and pH

    In this lab, students learn how a pH indicator can be used to detect the presence of CO2 when they exhale.

  • pH, 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.

  • History, pH, Acid & Base Theories, Strong vs Weak | High School, Middle School

    Video: Acid & Base Guys Video

    This video tells the story of how the definition of acids and bases has evolved from Lavoisier, to Arrhenius, Bronsted-Lowry, and Lewis.

  • pH, Titrations, Indicators, Strong vs Weak | High School

    Lab: Titration Curves

    In this lab, students graphically observe a plot of micro acid/base titrations and determine the equivalence point of each plotted curve.

  • pH, Titrations, Indicators, Strong vs Weak | High School

    Lab: Titration

    In this lab, students will learn the difference between strong, weak, and concentrated acids by carrying out various titrations.

  • pH, Acid Base Reactions, Chemical Change, Acid Rain | High School

    Lab: Seeing the Effects of Acid Rain

    In this lesson, students will prepare an environment and make acid rain to see how the acid rain effects the items in the environment.

  • pH, Indicators | Middle School, High School

    Lab: Detecting pH of Commonly Used Acids and Bases

    In this lab, students will use their knowledge of acids and bases to determine the acidity and basicity of every day items by measuring pH using several different methods for determination. Indications of pH may be determined using red & blue litmus paper, pH strips, and pH probes or pH meters.
