Lesson Plan: Investigating a Suspicious Drowning with Titrations
In this lesson, students take on the role of a forensic chemist who is tasked with investigating a suspicious drowning incident. Students will conduct a series of titrations on an evidence sample of water collected from the victim's lungs as well as on several water samples from local water sources (lakes, rivers, wells, etc.) Based on their findings, they will determine where the victim actually drowned.

Observations, Chemical Change, Acid Base Reactions, Chemical Change | Middle School, High 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, Acid & Base Theories, Strong vs Weak | Middle School, High 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.
-
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, 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.
-
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.
-
Acid & Base Theories, Buffers | High School
Lesson Plan: Preparation and Evaluation of Buffers
