How an Electric Water Heater Works
An electric water heater is basically a piece of wire that has
a high resistance and that must be kept from coming in direct contact
with water. Find out how silica makes an electric water heater safe with information from a science teacher in this video.

: Water Base Layer in a Seascape Oil Painting
Painting seascapes always requires a water base layer. Be chaotic, hit the canvas hard, don't evenly apply the paint layers. This gives the painting depth. English captions. (2:11)
: Water Shades in a Seascape Oil Painting
Shading the water in a seascape painting will add depth and dimension. Go over the darker areas with a deeper shade of blue. Add other highlights as well. English captions. (1:32)
Pressure and Density of Water
This video demonstrates how water pressure affects objects (like a can) at varying depths. It shows how water's weight presses on the objects (force per unit area). 1:37 min.

Jack and Jill should use a Pulley for that Pail of Water!
If only Jack and Jill had a pulley for that pail of water they would not have fallen down that hill! (low resolution animation)
Why Does Water Rise?
This short video shows an experiment where water is drawn up into a container as the oxygen is burned off. The water rises because they're heating up the air inside the beaker. As the heat went out, the air pressure start pushing the water up. the beaker exploded because it had so much force, that it bounced on the table. Run time 03:59.

The Great Stink - History of sewage - Thames River Water
Thames Water commissioned this short film mark the 150th anniversary of The Great Stink. In the hot summer of 1858, the stench of sewage in the River Thames so offended MPs that Parliament was suspended and the Government agreed to "take immediate measures for abating the dangerous nuisance caused by the noxious state of the Thames". A leading Victorian engineer, Sir Joseph Bazalgette, was commissioned to design and build a system of sewers which would remove the sewage from the Thames, sending
Step-By-Step Solutions for Algebra
Excellent video from Jimmy Chang, who has a master's degree in math and has been a math teacher at St. Pete College for more than eight years. Mr. Chang explains step by step how to solve problems in Algebra explaining the importance of showing all steps involved.
Snow Monkeys Play in the Water to Stay Cool
Snow monkeys are native to Japan. Watch these macaques cool off by playing in the water and learn in this video why there are snow monkeys in Texas. Run time 01:12.
Ecosystems and Material Cycles: Water, Carbon, and Sulfur
Professor George Wolfe discusses ecosystems and material cycles in this video from Thinkwell's online Biology series. The video uses lecture format along with illustrations and notes on a whiteboard to aid in the instruction of the water cycle, carbon cycle, and sulfur cycle. Run time 11:33.
Mudskippers- Fish Out of Water!
This fish out of water has adapted to live mostly on land. However, it still needs to learn how to outrun its enemies. Learn about these unique land fish and what adaptations they have for survival. Run time 02:05.
Running Water: How It Erodes & Deposits
Running water changes the surface of the earth by cutting away rock in one place, carrying this load and then depositing it in another place. This program explores the relationship of running water to the land. This is a well narrated video with amazing scenes.
Running Water II: Landscape Evolution
The Colorado River is a powerful geologic agent — powerful enough to have carved the Grand Canyon. This program focuses on how such carving takes place over time, looking at erosion and deposition processes as they relate to river characteristics and type of rock. The evolution of rivers is covered, along with efforts to prevent harmful consequences to humans.

This video looks at scientific research which predicts that this Greenhouse Effect may result in extreme conditions - altering conditions on earth. Run time 03:04.
A Basic Explanation of Global Warming
How does global warming work? Here is a quick explanation with graphics - presented by former American Vice President, Al Gore. Run time 01:05.
Using Cloud-Seeding (Geo-Engineering) to Solve Global Warming
This clip from the "Five Ways to Save the World" details a cheap, simple, and low-risk way to compensate for global warming.
If the reflectivity of clouds could be increased slightly, sufficient sunlight would be reflected to compensate for any future release of CO2 into the atmosphere. (09:37)
