Ch 2: Measurement and Problem Solving: Help and Review

About This Chapter

The Measurement and Problem Solving chapter of this High School Chemistry Help and Review course is the simplest way to master chemistry. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of measurement and problem solving in chemistry.

Who's it for?

Anyone who needs help learning or mastering high school chemistry material will benefit from taking this course. There is no faster or easier way to learn chemistry. Among those who would benefit are:

  • Students who have fallen behind in understanding the metric system, scientific notation and measurement and problem solving in chemistry
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about measurement and problem solving in chemistry
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Measurement and Problem Solving in Chemistry chapter exam.

Why it works:

*Study Efficiently: Skip what you know; review what you don't.

Measurements & Uncertainty in Science

1. 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.

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.

The Metric System: Units and Conversion

3. The Metric System: Units and Conversion

Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.

Unit Conversion and Dimensional Analysis

4. 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.

Significant Figures and Scientific Notation

5. 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.

Factor-Label Method in Chemistry: Definition, Examples & Practice Problems
