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...

Measurements are very important for scientists. It is especially important that the measurements be accurate. Think about how important accuracy is when you want to know if you are taller than a friend of yours, every inch counts. In...

What are the common errors made when students take measurements and how can they be avoided? A good deal of vocabulary associated with measurement errors is explained. Tips are provided for the student and the teacher in hopes of...

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...

Students will estimate various dimensions of objects located in a classroom. After estimations are completed, students will measure objects using appropriate measuring techniques for preciseness.

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.

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

Explore the "intelligent floor," which contains sensors that can track movements, and emulate the weighing technique associated with this technology. Explore the relationship between volume and mass and the difference between accuracy...

[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 task could form part of a classroom activity where students are encouraged to find as many different ways as possible to make different fractions such as 1/12 and then share their methods. While measuring cups would be helpful to...

Investigate how precise measurments and effective communication skills are needed when engineering and digging a tunnel.

The difference between accuracy and precision is explained, with a precautionary note about being aware of possible bias in the measuring instrument.

This lesson will explain the difference between accuracy and precision. It is 11 of 11 in the series titled "Accuracy and Precision."

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

The goal of the task is to stimulate a conversation about rounding and about how to record numbers with an appropriate level of accuracy, tying in directly to the standard N-Q.3. Aligns with N-Q.A.3.

In this science fair project, use a precision hydrometer to measure the amount of sugar in soda. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on...

[Free Registration/Login may be required to access all resource tools.] This learning opportunity examines two angles of working with error. Students will practice taking measurements with accuracy and precision and then consider the...

Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed...

This lesson will explain how to determine the precision of a measurement using laboratory glassware and report it accurately. It is 2 of 2 in the series titled "Reporting Volume Measurements."

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.

Hooda Math games provide students extra practice in a variety of math skills. Multiplication Bubble Pop Instructions: Solve multiplication problems, then tap correct bubbles to pop them before they reach the top of the screen! This game...

Take a look at this presentation which provides examples on how to determine the uncertainty in a measurement.

Integer Warp is a multi-player racing game that allows students from anywhere in the world to race one another while practicing multiplying integers!
