Chemistry, 2nd Edition Course
Many students struggle in high school chemistry. Even if they succeed in earning a good grade, they often still feel confused and unconfident. Why is this? And what can be done to help every student succeed in this vitally important course? Success in chemistry, according to veteran science teacher Professor…
The Mole
One of the most important concepts to master in an introductory chemistry course is the concept of the mole, which provides chemists with a way to "count" atoms and molecules. Learn how scientists use the mole and explore the quantitative definition of this basic unit.
Quantitative Reasoning in Chemistry—Density
Building on the ideas explored in the first three lectures, you examine a fundamental quantitative measurement in chemistry, density, and explore the real-world meaning of this measurement. You then solidify your understanding of this concept by working some basic density problems.
Advanced Molarity Problems
You are asked to take the concepts you learned about molarity in the last two lectures and apply them to a number of unfamiliar problems. These problems offer an opportunity to test your comprehension of the concepts you've been exploring.
The Science of Energy - Resources and Power Explained
Energy is, without a doubt, the very foundation of the universe. It's the engine that powers life and fuels the evolution of human civilization. Yet for all its importance, what energy really is and how it works remains a mystery to most non-scientists. For example:
  • Where does most of…
Solving Mole Problems
By solving problems involving moles, you refine the quantitative techniques introduced in earlier lectures while increasing your familiarity with this important chemical value.
The Self-Ionization of Water
After examining how different substances may behave when dissolved in water, you learn about the self-ionization of water and use this knowledge to solve problems. The lecture ends with a brief introduction to the pH of solutions.
Putting It All Together
In this final lecture, you tackle problems that require you to pull together all the knowledge you've acquired. Through these challenging problems, you build confidence in your ability to unravel new problems and pursue more advanced levels of chemistry.
The SI (Metric) System of Measurement
Next, you continue to lay a strong foundation for your understanding of chemistry by learning about one of the key tools you'll be using: the International System of Units (SI), or the metric system. This lecture explains why this system is so useful to scientists and lays out the prefixes…
Chemistry In Action Series, for Middle School

The films, and accompanying teacher materials, are a great asset for teachers and teachers in training to use to integrate video…
Matter And Chemistry Series, for Elementary
Specifically designed for and correlated to the curriulum of a elementary school science course, this series explores key topics on Matter and Chemistry and helps instructors to teach challenging concepts. The films, and accompanying teacher materials, are a great asset for teachers and teachers in training to use to integrate…
Energy - Forms and Conversion for Use
Episode 2 of The Science of Energy
Energy is a fundamental part of our universe--in a sense, the universe is energy. Here, Professor Wysession introduces you to the many fascinating forms energy takes, including potential, kinetic, mechanical, and thermal energy. He also explains how energy is measured to make you more fluent in "energy-speak" for the coming…
