About This Worksheet
This medium-level worksheet contains 18 problems designed for 12th Grade students practicing logarithmic scales. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.
Logarithmic scales are used throughout science to make sense of quantities that span many orders of magnitude — earthquake energy, sound intensity, light brightness, and chemical acidity. Understanding why scientists use logarithmic scales and being able to calculate with them is essential scientific literacy for the modern world.
- Interpret the Richter scale: each unit increase represents a tenfold increase in amplitude
- Apply the decibel scale to compare sound intensities
- Use the pH formula to analyze acidity and basicity
- Calculate how much more energy a magnitude-8 earthquake releases than a magnitude-6
- Determine the pH change when hydrogen ion concentration is multiplied by a factor
How to Solve: Worked Example
- Read the problem carefully.
- Identify what is being asked.
- Use what you know to find the answer.
- Check your work.
