This is a review lesson on the concept of precision vs. accuracy in the context of scientific measurement, intended to be used near the beginning of a Physics course. Young scholars practice measuring and reading scales accurately and...

This activity is an introduction to measurement, especially precision. Students should know the difference between precision and accuracy in measurement. They will be able to answer the questions: At what temperature does the mood object...

Students learn the metric units engineers use to measure mass, distance (or length) and volume. They make estimations using these units and compare their guesses with actual values. To introduce the concepts, the teacher needs access to...

Use this ten question quiz to assess what you know about accuracy and precision. You may keep taking the quiz until you get 100% of the answers right.

Learn about the topics of accuracy, precision, and significant figures in this section of a physics textbook. Chapter can also be downloaded in pdf.

Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal...

Students experience the engineering design process as they design and build accurate and precise catapults using common materials. They use their catapults to participate in a game in which they launch Ping-Pong balls to attempt to hit...

An interactive tutorial showing how scientists should report measurements from their experiments. Shows the basics in a way that anyone can understand.

This activity is an exercise in using various lab equipment for measuring the volume of a liquid. Data is recorded on a spreadsheet and analyzed to see which tool offers the greatest precision.

Students learn the conversion relationship between inches and centimeters through data collection. The data collected results from measuring items using inches and centimeters as the units. They use a TI-73 to input the data into lists...

In this self-scoring 15 question analogy practice quiz, students select to correct word to complete the analogy.

This module looks at the history of measurement, beginning with non-standard units, the advent of standard units (in this case metric), and when approximation or precision would be needed.

Use this virtual model to simulate the basic operations and accuracy of a micrometer while manipulating the physical parts of the object.

Learn how to measure the inside diameter, outside diameter and the depth of different parts. This interactive activity shows you six different calipers. Once you understand the exercise, then you can test your knowledge with a quiz.
