How to Determine Total Magnification
Explains how the total magnification is determined. Common mistakes of microscope use is also reviewed. This is a high school student's video from a biology video pod cast. Color and sound. 4:15 min.
Microscope - Elementary Science
This is a short, animated narrated video (03:38) that offers an overview about how telescopes work. Some of the narration is accompanied by English captions.
Magnified Images
This student-made video includes images with extreme magnifications of various parasites, insects, and cells set to upbeat music. Various facts are written underneath the photos. Some of the images include: dust mites, ants, butterfly tongue, mosquitoes, bee stinger, fish scales, aphid, fleas, allergy pollen, fungus, E. coli, red blood cells, fruit fly, velcro, and a ball point pen. The photos and information change quickly and may be too fast for younger readers. (9:08)
Elements of Life
This video slide show is accompanied by text "... Take a look around you! The chair you're sitting in, the tree see when you look out the window, and even you are made up of matter. Matter is anything that has mass and occupies space.
Elements are the simplest type of matter and have unique chemical and physical properties. An element is a form of matter that cannot be decomposed into simpler substances by ordinary chemical methods. As of the year 2000, there were 112 known elements, but j

Take a journey into an ear canal to see how the ear works to receive vibrations from sound. As the viewer travels into the ear canal, captions appear on the screen.
If you can't smell, you probably can't taste very well either. They are closely related functions. Receptor cells for taste and smell are located in the mouth and nose, respectively. As the receptor cells are stimulated, they send impulses from these organs to the brain's smelling and tasting centers, the cortices. For taste, impulses stimulated by the chemical compounds in food are sent to the gustatory cortex. For smells impulses stimulated by the chemical compounds in odors are sent to the ol
Did you ever wonder how your nose works? Did you know that the human nose can recognize about ten thousand different smells? Join twins Ingram and Everett as they learn about our sense of smell and parts of the nose. Run time 10:57.
If you can't smell, you probably can't taste very well either. They are closely related senses. This short video explains why. Run time 0:52 seconds.
The instructor uses a sketchpad program to describe and show examples of Equilateral, Isosceles, and Scalene triangles. An example of each is modeled with the definition of each explained. Clear, step-by-step instruction.
This is an amusing spoof of 'Dancing With the Stars'. This Sesame Street video shows a dance competition that is supposed to involve triangles, but the contestants are a little confused. Other shapes such as a hexagon and a square are introduced, in addition to the triangle.
In this video, Mr. Khan draws a box and two intersecting lines that produce several triangles. Mr. Khan proves that the area of these diagonal-generated triangles of the rectangle are equal. He goes over the formula for finding the area of a triangle. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The screen gets busy (and dark)--the viewer may want to open to 'full screen' to see everything. The sound is a little low. (04:35)
The Pythagorean theorem is a formula used to solve side lengths of a right triangle, and it is expressed as A squared plus B squared equals C squared. Â The instructor uses a document camera to model what the Pythagorean Theorem is and how to use it.
Explore went to China on a fact-finding mission led by Charles Annenberg Weingarten, a trustee of the Annenberg Foundation. During the three-week trip, the team discovered many of China's hidden gems: philosophy, art, education, and rural life. They also discovered how the country's hard-working and innovative leaders were working to solve issues of the environment, human rights, and public health.
Rural schools, where the vast majority of children in China receive
their primary education, are often below the standards of their urban
counterparts. About 80% of rural schoolchildren don't get past middle
school, and many face difficult life prospects as they become teenage
farmers and migrant workers. But at AnWu Elementary, the explore team
saw the results of the school's vigorous improvements, and students
share their big hopes for the future with

Overview of the the work of the famous painter of birds; video gives insight into what made Audubon stand out at the time.'John James Audubon (April 26, 1785 – January 2, 1851) was a French-American ornithologist, naturalist, hunter, and painter. He painted, catalogued, and described the birds of North America in a form far superior to what had gone before' (Wikipedia, 2009). (2:00)
