Weird US Plunges Into Bonne Terre Mine
From the History Channel (produced by KPI) in which they explore the strange subterranean world of a vast flooded lead mine. The Bonne Terre Mine was originally a lead mine, during the late 19th century. Now the mine is open for tours and is also known as a Scuba diving attraction. Video is good quality and has information for students studying these areas of the United States.

Mulitplyling Decimals - Part 3 of 3
This video is from Sal Khan about multiplying decimals using the problem: What is the cost of 14.6 gallons of gasoline at $2.70 per gallon?
Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly. (02:32)
Subtracting Decimals - Word Problem
This video is from Sal Khan about subtracting decimals using the problem: Leo has $4,522.08 in his bank account. He deposits another $875.50 and then withdraws $300.00 in cash. How much is left in his bank account?
Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly. (02:18)
In this video, Sal Khan discusses how CAM Plants are able to 'fix' carbon at night so they don't have to keep their stomata open during the day. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
This video introduces the concept of an electric circuit. It describes the difference between an open and closed circuit.
Here's a quick lesson in buoyancy. It compares the weight of an object in the air compared to in the water. English captions are at the bottom of the screen. The words are small so the viewer may want to open the video to 'full screen'.
This silde show ia a useful overview of organic macromolecules, including aspects of their structure and function. There is no narration and no music. The viewer may have to open the slide show to 'full screen' as there is smaller print on some of the slides.
Soil Texture - Environmental Science
Learn all about soil texture and how to test for clay, silt and sand. English captions are at the bottom of the screen. The words are small so the viewer may want to open the video to 'full screen'. Key vocabulary words include: sand, silt, clay, organic matter, porosity, permeability, and loam. Run time 02:22.
Marine biologist Tierney Thys asks us to step into the water to visit the world of the Mola mola, or giant ocean sunfish. Basking, eating jellyfish and getting massages, this behemoth offers
This is a short, animated narrated video (02:25) that has an experiment that shows how liquid expands as a result of heat. For safety reasons, this experiment may be demonstrated by an instructor as the experiment requires a small, open flame. Some of the narration is accompanied by English captions.
Transmission of Heat - Elementary Science
This is a short, computer-animated narrated video (03:13) that offers information about heat transmission using an experiment. Since this experiment requires an open flame, this experiment should be done in the presence of an adult/teacher. Some of the narration is accompanied by English captions.
Introduction to Waves
In this video, the instructor offers an introduction to transverse and longitudinal waves. In an easy-to-understand, straightfoward manner the instructor explains while using computer software. Because the instructor writes on a dark screen, the viewer may want to open this video to 'full screen'.
Amplitude, Period, Frequency and Wavelength of Periodic Waves
In this video, the instructor explores amplitude, period, frequency, and wavelength of periodic waves. In an easy-to-understand, straightfoward manner the instructor explains while using computer software. Because the instructor writes on a dark screen, the viewer may want to open this video to 'full screen'.
Prometheus and Pandora
This simple video is narrated and apparently illustrated by a young child. Prometheus was a Titan God who stole fire from Zeus and gave it to human mortals. Zeus punished him, by having him bound to a rock while a great bird ate his liver every day (only to have it grow back to be eaten again the next day). Zeus, still angry, then sent Pandora (the first woman), to further punish humans. Pandora had a box she was not supposed to open. She opens it anyway, and when she does a blac
"I, Too, Sing America" Poem by Langston Hughes
This is a video of a man reading Langston Hughes' poem "I, Too, Sing America" at an open mic night. The words are not on screen. The lighting makes it impossible to see the man's features. The sound quality is fine. (0:47)
How to Rationalize a Denominator
The instructor starts with a basic ptoblem to solve: one over the square root of two...then he moves on to more complicated problems. Mr. Khan uses computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The viewer may want to open the video to 'full screen' as the instructor fits a lot of information on a dark screen
What is GLAST? Gamma Rays Part 1
The Universe is home to numerous exotic and beautiful phenomena, some of which can generate inconceivable amounts of energy. GLAST will open a new window on this high-energy world. With GLAST, astronomers will have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists will be able to search for signals of new fundamental processes that are inaccessible in ground-based accelerators and observatories. GLAST's s
Change at the Top of the World
Marked by towering glaciers and vast expanses of tundra and open sea, the astonishing Arctic landscape exudes a feeling of immense power. But the region's ecosystem is actually one of the most fragile, and it is facing quick deterioration from man-made intrusions such as mining, oil drilling, and pollution - as well as global warming. Journey with explore to meet the region's people and find out how these issues are affe
Island Universes: The Nature and Origin of Galaxies
Prof. Webb describes the basic characteristics of galaxies, outline the methods we use to study them, and highlights some of the main results and open questions in the field of galaxy formation and evolution.
