Activity Overview

In this activity, students will become familiar with a number of scientific measuring devices. They will become familiar with measurement, precision, certain and uncertain values, and significant figures.


  • Take and record measurements using different measuring devices.
  • Determine significant digits and estimated values of measurements.

About the Lesson

The following questions will guide student exploration during this activity:

  • How does estimation factor into the process of taking measurements?
  • Which parts of a measurement are significant digits?

    The goals of this activity for students are:
    1. to determine the units of measurement for different measuring devices,
    2. take measurements using different measuring devices, and
    3. determine the estimated values and significant digits for various measurements.
