Teach your next acids and bases unit with fresh and engaging teaching ideas designed to offer your students the opportunity to:
 
1. Distinguish between acids and bases
2. Learn the models of acids & bases, namely, Arrhenius, Brønsted-Lowry, and Lewis.
3. Conduct experiments to classify substances as either acids or bases.
4. Conduct experiments to investigate the effectiveness of some common antacid brands in neutralizing an acid.
5. Read a passage and learn about the properties of strong acids, strong bases, weak acids, and weak bases.
6. Identify acids, bases, conjugate acids, and conjugate bases when given a chemical equation.
7. Calculate the pH, H+, pOH, OH- ion concentrations as well as Ka and Kb of acids and bases.
8. Read and learn about buffers and the impact of acid rain.

Teacher Guide
 
The resource can be easily integrated into your existing teaching materials, used as a stand-alone, or even as a review at the end of the unit.

Part 1:What Are Acids, What Are Bases?
 
In this part, students will cut and paste statements and pictures under acids or bases. This is a quick and great way to evaluate students’ understanding after they have been introduced to the properties, the models, and examples of acids and bases.
 
Next, students will perform a pH test to classify some common substances as acids or bases.
Option 1: Using universal Indicator Paper Slips
Option 2: Using Cabbage Juice Indicator
 
I have included the procedure, list of materials, and detailed information in the resource to guide you and the students.

Part 2:How do antacids work: A Neutralization Reaction
 
In this part, students will test the efficiency of three common antacid brands
in neutralizing an acid. They will experiment, make observations, and collect data. This is a great and fun way to make the lesson meaningful to students' everyday experiences. Details are included.
 
Part 3: Strong and Weak Acids and Bases Reading Sheet
 
In this section, students will learn about the characteristics that distinguish a strong acid from a weak acid and a strong base from a weak base. They will learn the terms ionization and dissociation in relation to acids and bases, plus more. After the reading, they will complete a worksheet with the information they read.
 
Part 4: Conjugate Acid-Base Pair
 
In this section, students will identify acids, conjugate acids, bases, and conjugate bases when given a chemical equation. They will work through many examples to challenge and deepen their understanding of the topic.
 
Part 5: Strong Acids And Strong Bases Calculations
 
In this section, students will complete some calculation questions involving pH, pOH, [H⁺], and [OH⁻] of strong acids and strong bases. This may be used as a way to evaluate students’ comprehension after the topic has been well taught, or as a practice exercise or homework.
 
Part 6: Weak Acids And Weak Bases Calculations
 
In this section, students will complete some calculation questions involving pH, pOH, [H⁺], and [OH⁻] of weak acids and weak bases. Just like in part 5, this may be used to evaluate students after the topic has been taught.
 
Part 7: Acids, Bases, and Buffers
 
In this section, students will read about acids, bases, and buffers. They will learn the importance of buffers in real life, the effects of acid rainand complete a post-reading worksheet
 
I am confident this resource will be a wonderful addition to your teaching toolbox and help your students explore acids and bases in a hands-on and meaningful way. They will get the chance to do experiments, work in teams, read passages + more. The list of materials is quite easy to find, and the setup doesn't require much time, which saves the teacher valuable time.
