Acids, Bases, and Their Interactions

Introduction to the lesson and overview of topics to be covered

What do you already know about acids and bases?

Acid and Base Structure

Distinct structures of acids and bases influence their properties

Properties of Acids and Bases

Acids contain hydrogen ions (H+), while bases have hydroxide ions (OH-)

pH Scale

Measurement of acidity or basicity of a solution on a scale from 0 to 14

Indicators and Color Change

Substances that change color in the presence of acids or bases to indicate pH level

Conclusion

Recap of key points and learning objectives

Definitions

Acid: A substance that donates hydrogen ions (H+) in solution
Base: A substance that provides hydroxide ions (OH-) in solution
pH Scale: A scale ranging from 0 to 14 used to measure the acidity or basicity of a solution
Indicator: A chemical that changes color in the presence of an acid or base to signify its pH level

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
