  Lab: How do Sinkholes Form? Mark as Favorite (12 Favorites)

  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.

  Lesson Plan: Explorations of Baking Soda and Vinegar Mark as Favorite (3 Favorites)

  In this lesson, students complete a series of simple lab experiments to better understand chemical reactions as well as differentiate between chemical change and physical change. Students will also be introduced to the pH scale, and have the opportunity to understand how chemical reactions can be used in real-world scenarios.

• 

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

  Lab: Hydrolysis of Salts Mark as Favorite (7 Favorites)

  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.

• 

  Acid & Base Theories, Concentration | High School

  Lesson Plan: Calculating pH, A Look at Logarithms Mark as Favorite (21 Favorites)

  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 Mark as Favorite (10 Favorites)

  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 Mark as Favorite (15 Favorites)

  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.

  Reaction Rate, Reaction Rate, Chemical Change, Acid Base Reactions | Middle School

  Lab: Bath Bomb Chemistry! Mark as Favorite (7 Favorites)

  In this lab, the students will work in cooperative groups to investigate how to make a scented, effervescent bath bomb and explore the chemistry needed to create them. Groups will test a variety of different variables in order to compare the reaction rate of each sample. Students will use the results to determine which variables are optimal for making and using bath bombs.
