Pediatricans are trained to treat infants, children, and teens. Regular check-ups are done by them to make sure that the young patient is growing at a proper rate and search for signs of diseases. All doctors must finish college and 4 years of medical school. Then, they complete 3-8 years of training (residency), depending on their specialty. Physicians must continue training throughout their careers, keeping up with medical advances. This two minute video has a script and shows a pediatrician a
Unsolved History- Military: Battle of the Alamo
In the year 1836 the Alamo was the scene for one of the most spectacular marches in military history.This 3:42 long video explains the march of the Mexican soldiers that was unheard of at that time.
The battle lasted five hours and the Mexicans. Six weeks later the Mexicans were defeated. The video explains two sides of the battle of the Alamo. This is a good video to show students as it explains what this battle means to Mexicans.
The Alamo (2:37)
The cause and effect of the battle at the Alamo. The video also explains why the event has become an icon of history and why, in losing the battle, the Americans gained a cause and later victory. Not much detail.
3D Street Art With Julian Beever
Julian Beever painting 3-dimensional pictures on sidewalks and streets is the subject of this 3:17 minute video. This could be used by art teachers to show how perspective is done or just as motivation. A real eye-catcher, but the music may be distracting.
The Mexican American War
Conflict between U.S and Mexico started when Mexico insisted that its northern border lay along Nueces River, while U.S.claimed that it was farther south along Rio Grande. President Polk sent Zachary Taylor to the troubled area, but the two sides clashed and U.S. soldiers were killed, leading to Congress' declaration of war. The Mexican War gave U.S. more land, but led to more conflicts between free/slave states. This four minute video explains this and is accompanied by text to make it easier t
Contemporary Perspectives in Distal Radius Fracture Fixation
Wrist fractures, those injuries involving the distal radius, the distal ulna, and the joints about these bones, are some of the most commonly sustained fractures in any age group. With such a large number of injuries encountered, the effort to return patients to their normal activities has driven remarkable changes in treatment methods. UW physicians Matt Lyons, Jeffrey Friedrich, Douglas Hanel, and Jerry Huang discuss the history of wrist fractures and how the recently updated AAOS guidelines a
The International Immunogenetics Information System
Created by Marie-Paule Lefranc from Universite Montpellier, the international ImMunoGeneTics (IMGT) information system? "is a high-quality integrated knowledge resource specializing in immunoglobulins (IG), T cell receptors (TR), major histocompatibility complex (MHC) and related proteins of the immune system of human and other vertebrate species." The site contains sequence databases, genome and structure databases, web resources, and other interactive tools. With hundreds, if not thousands, of
The Whyfiles Spring Break Edition: Bad News on Skin Cancer
You are unlikely to meet anyone these days who has never heard that UV radiation from the sun can cause skin cancer, but scientific inquiry into this unfortunate fact is far from over. This Whyfiles feature offers an in-depth explanation of the sun-skin cancer connection, beginning with a highly readable, explanatory introduction to UV radiation, forms of skin cancer, and the ozone layer. This background information sets the groundwork for the next section, an intriguing look at epidemiological

Stem Cell Task Force
This Web site from the National Institutes of Health (NIH) provides an overview of the activities of an NIH task force established to move the stem cell research agenda forward. The section titled Scientific Research may be of particular interest to researchers in this area. It provides links to the Web sites of stem cell-related research at a number of NIH institutes, as well as an extensive information index, a FAQs page about stem cell research, information on funding opportunities, and much
Drilling for oil in the Arctic National Wildlife Refuge (ANWR) in Alaska has been a topic of debate for many years. Although initial exploratory drilling has not yet been authorized by the government, this site presents some technologies that could eventually be used to find and extract oil without damaging the land. Nine articles describe different drilling methods, spill prevention tactics, exploration techniques, and more. One topic is 3D reflective seismic technology, which is used to help a
Low Dose Radiation Research
The US Department of Energy's Low Dose Radiation Research Program supports research that investigates the health risks from exposure to radiation at low levels. This Web site provides an overview of radiation biology, up-to-date information and archived results from program-related research, and other resources for the benefit of researchers and the general public alike. Some research projects include comparing low dose radiation to endogenous oxidative damage, determining thresholds for radiati
Plants in Motion
Roger P. Hangarter of Indiana University's Department of Biology has created this wonderful collection of time-lapse photography that allows us "to see the movements of plants and clearly demonstrates that plants are living and capable of some extraordinary things. " The videos available show a broad range of plant growth phenomena, including germination, circadian responses, phototropism, and much more. The movies are fun to watch in and of themselves, but don't miss out on the informative desc
Since its inception over a half century ago, the Soil Association has "been working to raise awareness about the positive health and environmental benefits of organic food and farming and supporting farmers in producing natural food consumers can trust." Originally formed by a coalition of inspired scientists, nutritionists, and farmers, the Soil Association is now the leading organic farming and food certification and campaigning organization in the United Kingdom. Although primarily geared tow
The Messier Catalog
The Students for the Exploration and Development of Space of the University of Arizona maintains The Messier Catalog Web site. Named after the French astronomer who first discovered the objects, the catalog describes and features what are considered to be some of the most beautiful nebulae, star clusters, and galaxies in the sky. Visitors can read about Messier and about each individual object in the actual catalog, which includes a picture, its distance, brightness, the history of its discovery
