Using a measurement technique called measurement and uncertainty, students will measure the speed of sound. Students need to use a microphone and Vernier LabQuest to record and measure the sound of a finger-snap echo.

By the end of this section, you will be able to do the following: Determine the appropriate number of significant figures in both addition and subtraction, as well as multiplication and division calculations and Calculate the percent...

This is a lab activity that allows students to collect data to practice using effective measurement. While other authors have produced similar labs, this version includes uncertainty analysis consistent with effective measurement...

A really nice distinction here in this longish piece from the Bellevue Community College. It's not just accuracy vs. precision, but also error vs. uncertainty. This is a necessary additional consideration for any paper on the topic.

[Free Registration/Login Required] Intro to Physics - Students will learn about the two main types of uncertainty while dealing with measurements - Explicit, Implicit - along with the concept of percent uncertainty.

A brief overview of the use of certain and uncertain digits in measurement.

This lesson explains why/how uncertainty is used and why it is important to be aware of it when making measurements. It is 2 of 4 in the series titled "Introduction to Uncertainty."

[Free Registration/Login Required] In this interactive you will measure the box against the three different rulers to best determine the height of the box with each ruler. You will need a sign-in to access this media, but it will be well...

This resource engages learners in using scientific data to analyze a 150-year dataset from Lake Mendota in Madison Wisconsin reflecting seasonal ice cover.

This lesson will define certain and uncertain digits in measurement. It is 1 of 3 in the series titled "Identifying Certain and Uncertain Digits."

By the end of this section, you will be able to associate physical quantities with their International System of Units (SI) and perform conversions among SI units using scientific notation; relate measurement uncertainty to significant...

This interactive site helps students determine the appropriate number of significant figures in both addition and subtraction, as well as multiplication and division calculations. They also calculate the percent uncertainty of a...
