Chemical equations
Filled with real-life demonstrations that support instructive written examples, this program reinforces the basic principles of solving equations for chemical reactions. A brief historical overview describes Marie and Antoine Lavoisier's establishme...
Protecting earth's atmosphere
This Science Screen Report explains the importance of the gas layers surrounding our planet and the consequences of changing them. Detailing how the atmosphere and the Sun's radiation create the greenhouse effect, the program outlines ways that huma...
Brain and nervous system: your information superhighway
This program explores the brain and nervous system, using the analogy of computers and the Internet. Topics discussed include electrical impulses and how nerve messages travel; parts of the brain and their functions; how the brain and spinal cord ar...
The light reaction
The light reaction is explored in depth with computer animation. The program follows the path of the electrons through the P680 and P700 photosystems, and eventually out into the stroma, where they are used in the dark reaction.
The halogens
The halogens is the only group that contains elements representing all three familiar states of matter at standard temperature and pressure. Segments in this program include Exploring the Halogens (properties of the halogens); Fluorine: The Painless...
The actinide series
Most elements in the actinide series were created artificially; only thorium and uranium are found in nature. Segments in this program include "Exploring the Actinide Series" (properties of the actinides); "Uranium: Stealth Boomer" (the use of urani...
Chemical reactions
What do fireworks, a fried egg, and a rusting truck have in common? They all involve chemical reactions. This program illustrates the mechanics of chemical reactions in five sections: Chemical Reactions (reactants and products, state changes, diatom...
The periodic table
Much more than a list of elements, the periodic table is a snapshot of how matter is organized on Earth and throughout the universe. Divided into five sections, this program looks at the history and components of the periodic table: The History of t...
Breathing
This program begins by looking at a typical day in the life of a cystic fibrosis sufferer. The structure and function of the lungs are seen through a mixture of computer graphics and real-life video. The problems encountered with cystic fibrosis are...
Cells: the building blocks of life
This video takes a close-up look at the lowest common denominator of all life: the cell. It illustrates essential cellular processes - transportation of materials, communication, energy transfer, protein-building, waste disposal, movement, and the a...
