Elements, Atoms, and the Periodic Table
In the next three lectures, you cover some fundamental topics that you'll need before you can launch into your study of chemistry. You examine the basic building blocks of matter--elements and the atoms that constitute them--and you learn how to interpret the information about elements presented in the periodic table
The Mystery of Matter - The Search for the Elements
PBS
THE MYSTERY OF MATTER: SEARCH FOR THE ELEMENTS is an exciting three-part series about one of the great adventures in the history of science: the long and continuing quest to understand what the world is made of. Three hour-long episodes tell the story of seven of history's most important scientists…
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…
Surface Energy: The Interfaces among Us
Episode 12 of The Nature of Matter
A surface is a discontinuity, or interface, between one phase of matter and another. Focus on this crucial boundary, which affects everything from a spacecraft reentering the atmosphere to the efficient washing of clothes. Explore surface phenomena such as films, surface tension, and catalysts.
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…
Heat - The Transfer and Flow of Energy
Episode 3 of The Science of Energy
One of the first forms of energy that humans learned to use is heat. You'll examine three ways heat flows (radiation, convection, conduction); make sense of the heat flow equation and the concept of entropy; and go inside the inner workings of a "heat engine" machine.
The Nature of Matter - Understanding the Physical World
Discover how the immense variety of matter--stars, mountains, plants, people--is made by a limited number of elements that combine in simple ways. In the engaging lectures of The Nature of Matter, no scientific background is needed to appreciate everyday miracles like a bouncing rubber ball or water's astonishing power to…
Every Breath We Take - Understanding Our Atmosphere
BBC
The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. This remarkable film reveals…
The Future of Materials
Episode 24 of The Nature of Matter
Close your study of the nature of matter by looking ahead at ambitious goals for future materials, and review examples of past science fiction that's now science fact. Achievements like the Moon landings and the Internet suggest that nanoscale technologies, a cure for cancer, and other dreams may one day…
Stoichiometry Problems
You extend your study of stoichiometry to consider more complex problems involving volume, molecules, and energy.
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…
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.
