Lesson: Measurement Accuracy and Precision Physics • 9th Grade

In this lesson, we will learn how to define measurement accuracy and precision and explain how different types of measurement errors affect them.

Lesson Plan

Objectives

Students will be able to

  • define what makes a measurement accurate or inaccurate,
  • define what makes a set of measurements precise or imprecise,
  • compare random errors and systematic errors in terms of their effect on measurement accuracy and precision,
  • define zero errors and describe their effect on measurement accuracy and precision,
  • explain the usefulness of repeated measurements.

Prerequisites

Students should already be familiar with

  • measured quantities and units.

Exclusions

Students will not cover

  • the operation of specific measuring devices,
  • the quantitative treatment of uncertainties.
