Objectives

• Students will understand the concept of logarithmic scale and its applications.
• Students will be able to use logarithmic scale to solve mathematical problems.
• Students will develop critical thinking skills through problem solving.

Materials

• Whiteboard and markers
• Handouts with logarithmic scale examples
• Calculators
• Homework assignments with answers

Procedure

1. Introduction (5 minutes)

   • Review the concept of exponents and ask students if they have ever heard of logarithmic scale.
   • Give examples of logarithmic scale in real life (e.g. earthquakes, decibels, pH scale).

2. Explanation of logarithmic scale (10 minutes)

   • Write the formula for logarithmic scale on the board:

     logb x = y

   where b is the base (usually 10), x is the number we want to find the logarithm of, and y is the logarithm value.

   • Show examples of logarithmic scale on the board. Explain that logarithmic scale compresses a wide range of numbers into a smaller range, making it easier to compare numbers that differ by orders of magnitude.

3. Practice problems (10 minutes)

   • Provide handouts with logarithmic scale examples and give students time to work on them.

4. Homework (5 minutes)

   • Assign logarithmic scale problems as homework.

5. Conclusion (5 minutes)

   • Review the concepts learned in the lesson.
   • Remind students to complete the homework assigned.
