Ch 1: Tools & Methods of Scientific Measurement

About This Chapter

We can help you learn more about units and measurement and how they're used in science. These interesting lessons and quizzes are a quick way to measure your understanding of this subject before you take a placement exam or class test.

Tools & Methods of Scientific Measurement - Chapter Summary

Our instructors explain the current SI standards used in science as well as the base and derived units that make up this measurement system. You'll also learn about dimensional analysis and unit conversion as they relate to scientific measurement. How to account for uncertainty in these measurements is also discussed.

The common scientific instruments used to take measurements are outlined, as well as the concepts of scientific notation and significant figures. This chapter will prepare you to do the following:

  • Identify the seven standard SI units used by scientists
  • Understand the base and derived units that make up the SI system
  • Take scientific measurements with precision and accuracy
  • Identify some of the common scientific measuring tools
  • Recognize and use scientific notation accurately
  • Explain how percentage error works in scientific measurements

Take the lesson quizzes and chapter test before or after you review these lessons to see how well you understand the subject matter. If you need to review just one part of a video lesson again, use the video tabs feature in the Timeline to jump directly to that section. Our instructors are available to answer your questions if you have difficulty. All our study materials are available for you to access at any time on your tablet, computer or mobile phone.

Current SI Standards in Science

1. Current SI Standards in Science

After completing this lesson, you will be able to explain why standard units are used in science, and list and describe the seven standard SI units scientists use. A short quiz will follow.

Elements of the SI: Base & Derived Units

2. Elements of the SI: Base & Derived Units

Discover what we mean by SI units. Then explore SI units further by learning about all the base units, and several examples of the derived units that make up the system.

Unit Conversion and Dimensional Analysis

3. Unit Conversion and Dimensional Analysis

How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.

Measurements & Uncertainty in Science

4. Measurements & Uncertainty in Science

In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.

Scientific Measurement Instruments: Types & Uses

5. Scientific Measurement Instruments: Types & Uses

There are many valuable measuring devices in science. This lesson will highlight how to use three such precision instruments: Vernier calipers, screw gauges, and physical balances.

Significant Figures and Scientific Notation

6. Significant Figures and Scientific Notation

Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.

Scientific Measurements: Accuracy, Precision & Percentage Error

7. Scientific Measurements: Accuracy, Precision & Percentage Error

Accuracy, precision, and percentage error all characterize scientific measurements and tell you something about how good the measurements are. In this lesson, learn what these terms mean and how to calculate percentage error.
