Welcome to IBPvo
Researchers at the University of Tennessee have developed "an Internet2-enabled personal video recorder (PVR) service" that is freely available at the first site. The service is based upon Logistical Networking, which is a new kind of data management that transfers and stores data through a distributed network environment. Users can download the software and register for free; however, only users connected to the Internet2 backbone will be able to use the service.

University of Wisconsin-Madison: What is the Ultimate Fate of the Universe?
This website, created by Molly Read for the Observational Cosmology Group at the University of Wisconsin-Madison, discusses the ancient questions about the development of the universe, its limits, and its fate. After reading a brief history of the field of cosmology, students and educators can learn about Olbers' Paradox, Hubble Expansion, the big bang theory, electromagnetic spectrum, and cosmic microwave background. The text contains many helpful diagrams, images, short videos, and links to a
Next Generation Space Telescope (NGST) Observatory Architecture and Performance
Although not scheduled to be launched until 2011, design plans for the Hubble Space Telescope's replacement are already underway. This research paper describes some of the architectural and performance specifications slated for the Next Generation Space Telescope (now called the James Webb Space Telescope). The seven-meter primary mirror will be hexagonal and made up of twelve smaller one-meter mirrors, allowing the observatory to see "objects 400 times fainter than seen from large groundbased t
The first Web site related to lubrication is presented by SynLube.com and its relevant page is entitled Basics: What You Need to Know About Lubrication (1). Visitors can learn why lubrication is so important to mechanical devices, why oil needs to be changed in your car, what synthetic oils can do, and more. Although the site is for a manufacturer of synthetic oil, there is a good amount of interesting physical science information. The second site provides an educational resource activity by The
This Web site from Animal Planet offers visitors the very latest news about animals around the globe. Scroll along the map of the world, and then click on an icon. A pop-up window will appear with a synopsis of a news story, a link to the full story, and a list of related features on the Animal Planet Web site. A key to the map icons is provided. The full news story page also provides general information and trivia about each animal. This is a great resource for anyone wishing to keep informed a
DNA from the Beginning: An Animated Primer on the Basics of DNA, Genes and Hereditary
Maintained by the Cold Spring Harbor Research Laboratory and the Josiah Macy, Jr. Foundation, this animated DNA primer (last mentioned in the February 19, 1999 Scout Report) now has three major sections -- Classical Genetics, Molecular Genetics, and Genetic Organization and Control. Each section covers several concepts by description and in animation, along with interviews and biographies of scientists, a quiz to test your understanding, and related Web links. This is a well-organized site with
Nonindigenous Aquatic Species
This US Geological Survey database provides information on nonindigenous aquatic species for resource professionals and the general public. Distribution maps and species information for a variety of aquatic vertebrate, invertebrate, and plant species includes photos, description of the life cycle, native and non-native habitat range, and potential impacts the non-native species has on its habitat. The site is easy to navigate; users can find information by species name, state, or drainage basin.
What You Always Wanted to Know About Salt
The What You Always Wanted to Know About Salt Web site is maintained by the nonprofit organization the Salt Institute. Information on nearly every aspect of salt can be found here, including salt facts, properties of sodium chloride, salt deposits in the US, the various uses of salt, salt in the winter, the history of salt, and much more.
The US Department of Interior Web site offers a hot topics section that currently includes information about coalbed methane. The links include a fact sheet entitled "Coalbed Methane--An Untapped Energy Resource and an Environmental Concern."

The Paleontological Society
The Paleontological Society, an international non-profit organization founded in 1908, created this Web site devoted to the advancements in paleontology. The site allows paleontologists access to abstracts in a few journals including Paleobiology. Prospective students will discover grant opportunities. Media representatives with questions about the history of life on earth can find contacts for paleontologists. Scientists can also learn about the society's Distinguished Lecture Program, which fe
Building Tetrahedral Kites
Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.
Students learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts and occluded fronts) and how these fronts are depicted on a surface weather analysis, or weather map. Students also learn several different ways that engineers help with storm prediction, analysis and protection.
Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.
