Logarithmic Scales and Applications
Students will explore real-world applications of logarithms, such as pH, Richter scale, and decibels.
Key Questions
- Analyze why logarithmic scales are used to represent certain real-world phenomena.
- Explain how a logarithmic scale compresses a wide range of values into a manageable scale.
- Compare the intensity differences represented by small changes on a logarithmic scale.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
