Ocean Pressure and How it Effects Ocean Exploration
Ninth segment of the Ocean Odyssey describes Ocean Pressure and how that limits the depth to which people can dive. Produced specifically for students and is suitable for elementary and older students.
(This is an Emmy award-winning series of instructional programs that introduces students in grades 3-5 to NASA and integrates mathematics, science, and technology through the use of Problem-Based Learning (PBL), scientific inquiry, and the scientific method. The series seeks to motivate s
Google Ocean, Anyone?
Ocean explorer Robert Ballard takes us on a mindbending trip to hidden worlds underwater, where he and other researchers are finding unexpected life, resources, even new mountains. He makes a case for serious exploration and mapping. Google Ocean, anyone? Run time 18:17.
Arabia's Cycle of Life - Reef Symbiosis
A look at the symbiotic relationships in fringing reefs. The video starts with an exploration of the birds, invertebrates and fish that live in and off the shallow waters and tidal pools and moves on to explore some of the marine life and the symbiotic relationships in the shallow coral reefs. Run time 06:36.
Amphibians May Give Us Clues to Our Changing Climate
Changes in amphibian populations may offer clues to changes in our climate. In the Rock Mountains scientists spend their summers studying wind, weather, plant life and amphibians. The salamander population in this area fluctuates year to year and they are trying to determine if this decline is caused by global warming or humans. Run time 03:14.
Tom Price, Ultimate Green Farmer
He's a great example of what we all should try to become. With a unique composting facility, Price does his part to pitch in to save the environment.
Japanese Nuclear Reactors Explained for Students
Mr. Mac explains to his students what happened to the Japanese nuclear reactors, in kid-friendly language and drawings. (Teacher is John McChesney, Director of Rock-it Science, a Silicon Valley nonprofit organization.) (14:29)
Lasers are more than just science fiction. Learn about lasers, how they work and how they are classified in this short, computer-animated video. The following key concepts will be briefly covered: lasers, laser technology, atoms, energizing atoms, energy states, photons, mediums and medium types, how lasers focus photons, and laser classifications.
Does Light Travel in a Straight Line?
Light travels both in straight lines and through reflection,
which is a process in which light enters a prism and bends. Discover how light bends when going from one material to another with information from a science teacher in this video.
Why Is the Sky Blue?
In this "Ask an Astronomer" episode (03:05), Dr. Carolyn Brinkworth fills us in on what the color of the sky has to do with finding life on distant planets.
In this video from the Encyclopedia of Physics Demonstrations, learn about total internal reflection. A laser beam is aligned so that the light passes through a water tank and out through an opening. As water flows out of the opening, observe how the laser beam remains trapped in the water stream because of total internal reflection. See how the light follows the path of the water even when the flow changes. Run time 01:03.
Light and Color
In this video segment adapted from Shedding Light on Science, learn about the dispersion of light, the electromagnetic spectrum, and how sunlight contains a range of wavelengths (photons of differing energy). Isaac Newton investigated sunlight by shining it through a glass prism; after the prism refracted the light, he saw a spectrum of colors. He recognized that sunlight was made up of many colors, which could not be further separated when passed through a second prism. Drops of water in the ai
13th Century Astrolabe Demonstration
Rather than demo another new technology, Tom Wujec reaches back to one of our earliest but most ingenious devices -- the astrolabe. With thousands of uses, from telling time to mapping the night sky, this old tech reminds us that the ancient can be as brilliant as the brand-new. Run time 09:26.
On the Surface Surface science examines how surfaces react with each other at the molecular level. The atoms at the surface are different than those atoms in the center of an object, making the atoms much more reactive than those inside. This program explores a variety of real world applications of this particular property.

Really Foamy Reaction
Elephant toothpaste is the name given to the catalyzed decomposition
reaction of 30% hydrogen peroxide that uses soap to collect the oxgen
gas that is produced. It is a favorite of most students at chemistry
Norse Mythology: Day and Night, Sun and Moon
At first the world was a dark and gloomy place, even with the great open sky. The Gods had to create the sun and the moon. They also had to invent day and night to make his time better. Night was the daughter to Narfi, she was beautiful creature. Night and her second husband had a daughter named Earth. Night and her third husband named Dawn and they had a fair hair shining sun named Day. The sun and t
The Mixed Up Chameleon
Except for catching flies and changing colors occasionally, this chameleon doesn't find life very exciting. When a surprise visit to the zoo makes this wistful lizard realize it can change its shape and size as easily as its color, it ends up wanting to be like all the animals in the zoo at once--with hilarious results. Book is by Eric Carle.
Emily Dickinson – Her True Self
A biography that is easy for students to follow with some excerpts from her poetry. A must watch for students preparing to study her work. Historical insights as well.
