Centripetal Force: the Roller Coaster
What can we learn about physics from an amusement park ride? This videosegment, produced for Teachers' Domain, uses roller coaster footage to demonstrate that what really keeps people pinned to their seats as a roller coaster hurtles through a loop isn't just the seat belts, it's centripetal force. To reinforce this important scientific principle,a physics teacher successfully swings a cup of water around his head without spilling a drop. Run time 04:40.
The Kidney and Nephron
This is an overview of how the nephrons in the kidney filter blood and re-absorb water and other molecules. Mr. Khan uses computer software (with different colors for clarification and emphasis) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
Anatomy of a Kidney
There is a very brief video with still images of the kidney. This is a quote from the video:
"This cross section of a kidney, almost three times life-size, shows its blood supply and one of the filter tubules, a nephron, highly magnified. The nephron is a highly specialized coiled tubule measuring up to one inch in length. There are more than one million nephrons in each kidney. They function as the kidney's filter units. The kidneys filter unwanted materials from the blood and regulate th
Learn How the Kidneys Work
How do our kidneys filter our blood stream? This video deomonstrates and explains how our kidneys work by making a model using a water bottle, fish tank tubing, funnel, coffee filters, food coloring and water. Run time 03:52.

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
Hoover Dam and Hydroelectric Power Plant Tour Part 1
This video is a series of video clips taken when visiting the Hoover Dam and Hydroelectric Power Plant back on December 28, 2008. Hoover Dam is located at Lake Mead at the Arizona and Nevada State line and just East of Las Vegas on US Highway 93. The highway goes over the dam, but a by pass bridge is being built across the Colorado River just down stream from the dam due to be completed in September of 2009. Video part 1 mainly shows the outside area of the dam as viewed from the visit
Learning about Mosquitoes and Life Cycles with Curious George
The children head outside and discover things swimming in the water inside the bird bath. They learn about the four different stages of a mosquito (egg, larvae, pupae, adult) as well as what an entomologist is.
Fuel Cells- Hydrogen Energy
In this video you see a battery that runs on water and it discusses how this kind of battery may be in our cars and homes in the very near future. This battery uses hydrogen as fuel. The cleanest and easiest to find form of hydrogen is water. Run time 02:39.
The Large Intestine
This short video shows the stage in digestion where the large intestine works. It explains that during digestion water is reabsorbed into the large intestine.

How to Make a Cloud in a Jar
We have all seen clouds in the sky- now make them in a jar! Using a jar with hot water and a match, see how the jar fills with cloud-like smoke. An adult must be present for this experiment.
Instructor uses a white board to model factoring trinomials. Examples include when both B and C are positive, when B is negative, and when C is negative. Instructor also models how to check solutions. (7:54)
Dinosaur Extinction Asteroid
At the end of the Cretaceous, 65 million years ago, not only did the dinosaurs disappear completely, but so did flying reptiles (pterosaurs), and marine reptiles (ichthyosaurs and plesiosaurs). In fact, between 60 and 80% of all animal species, including many marine forms, disappeared. Most turtles, crocodiles and primitive birds also disappeared but some survived to give rise to modern forms.
There have been numerous theories to account for the extinction of dinosaurs. But during t
Mixture Word Problems - Algebra Help
Using information to write an equation and solve a word problem, the instructor uses whiteboard to demonstrate. Students learn to solve "mixture" word problems -- for example, adding two acid solutions together, or adding water to a sugar solution. Students then set up a chart based on the mixture formula, which states that the amount of solution times the percent of acid = amount of acid (or the amount of solution times the percent of sugar = amount of sugar). The chart is then used to set up t
Mixture Word Problem
Writing an equation and finding the amounts of two different antifreeze solutions that must be mixed to obtain the desired antifreeze solution. Suitable for high school students. Instructor uses white board and markers.

Two minute video shows geckos in/on the water. Excellent footage. Great for introduction into anmial unit. Perhaps a compare and contast with a lizard. Run time 02:28.
Join Nana as she explains water flow and how flowers drink. She uses a long stem carnation, food coloring, water and glasses to demonstrate how flowers "drink" their nutrients. Nana also addresses the xylem and phloem inside the stem of the flower. The Kids Know It movies bring your student on a fun and interactive journey through the world around us. Run time 06:55
Amusing introduction to hydrogen
An amusing introduction to the properties of hydrogen. Illustrates that hydrogen is lighter than air, with a balloon. A wild-haired professor discusses the element, that it's part of water, and introduces the notion of deuterium. Finally, the hydogen balloon is exploded with some fire.
