Testing Java Applets
This collection of Java applets comes from a mathematics professor at Kennesaw State University. Most of the utilities are used to demonstrate graphical representations of different kinds of equations. For example, the Quadratic Functions section contains applets that let the user change the values of the equation's parameters, and the graph is updated to show how the underlying function changes. There are also applets that help users visualize the processes of differentiation and integration, a
Collaborative Lesson Archive
The Collaborative Lesson Archive of the University of Illinois is intended to be "a forum for the creation, distribution, and archival of education curricula for all grade levels and subject areas." The main page contains links to lessons organized by individual grade levels from kindergarten to beyond the twelfth grade. Once chosen, users are presented with a list of subjects including geography, science, and math, among others, which then contain various lessons. The sixth grade science sectio
Learning from the Fossil Record
Another interesting and helpful resource from the University of California Berkeley Museum of Paleontology is the Learning from the Fossil Record Web site. Educators will find a list of over twenty fossil related classroom activities presented by different authors with titles such as Building a Topographic Model, Determining the Age Of Rocks and Fossils, Fossilization and Adaptation, the Dinosaur Body Structure, Microfossils, and other interesting subjects. The detailed descriptions include ever
Access To Space
Access To Space is a Web site created by NASA's Goddard Space Flight Center. It is partly used by individuals and businesses interested in putting something into orbit, but it is also a very large and growing information source. The Mission Design section has a database of missions (both in progress and underway) and access mode information about various launch vehicles. It prompts for registration, but visitors can log in as guests. The Tech Space and Jump Space sections have many links to aero
Einstein's Origami Snowflake Game
Rick Nordal has created this fun website about the art of origami. The website is essentially an online paper-folding game. Graphic images are used to lead the visitor through the step-by-step process of folding paper into various geometric shapes in order to make a snowflake. The games involve folding a paper into a series of geometric shapes as quickly as possible, testing "a player's folding speed as well as his or her strategic thinking skills." Other games provide more fun with origami and
10th Report on Carcinogens
The US Department of Health and Human Services has recently made available its 10th Report on Carcinogens (RoC), as prepared by the National Toxicology Program located at the National Institute of Environmental Health Sciences (NIEHS). Users may view the entire report on this Web site provided by Environmental Health Perspectives, a peer-reviewed journal published by NIEHS. The RoC is an authoritative study that identifies and examines substances that pose a potential carcinogenic hazard to huma
Nuclear Physics Group
This website features the Nuclear Physics Group at the University of Birmingham's research related to understanding nuclei properties by studying the behavior of their constituents. Visitors can learn about the investigations undertaken by the five subgroups: Relativistic Heavy Ion Collisions, Exotic beams studies, Laser Spectroscopy of Unstable Isotopes, Positron Emission Tomography, and Nuclear Power Energy. Students and educators can discover how under high temperature and density a quark is
All about glaciers
The National Snow and Ice Data Center created this website to educate everyone, from grade school students to glaciologists, about glaciers. At the Data and Science link, researchers can learn about glaciological organizations, publications, and research projects as well as how to obtain glacial data. Students and educators can find a glaciology glossary, answers to many of their questions, and amazing images of glaciers at the General Information link. The website also provides a detailed portr
Fear of Physics
The Fear of Physics Web site contains more than twenty interactive physics related activities. Everything from things that spin, sound, atoms, collisions, and the Doppler effect are included. The Speed and Acceleration link teaches about movement by allowing users to choose two vehicles and change their position, speed, and acceleration. After pressing the GO button, the program runs, and students get to see how the chosen variables affect the vehicles' movements. A great collection of online le
Air Travelers
Offered by the Science Learning Network, the Air Travelers Web site is "an introduction to the basic principles of buoyancy, properties of gases, temperature, and the technology involved in hot air ballooning." Four activities are described along with any materials needed, directions, and questions that help students understand the concepts. A bonus activity is also provided that explains how to build your own hot air balloon using common household items.
Optical Storage in China: A Study in Strategic Industrial Policy
This unique paper, published in September 2003, discusses the current state and development of the Chinese high-tech industry. The author "begins with a brief overview of industrial policy for the electronics sector in East Asia, then discusses the relevant policies for two successive generations of optical storage: Video CD and DVD." The analysis of Video Compact Disc technology and its use is particularly insightful, since it is relatively unknown outside Asia. A brief look at other areas in t
Two on Powered Flight
Although the centennial anniversary of the Wright Brothers' groundbreaking achievement has come and gone, these two sites provide a unique glimpse into past events and future prospects. First, the companion website to a December 16, 2003 NOVA episode offers a retrospective on the Wright Brothers' Flying Machine. Several interactive features and picture galleries are provided. Additionally, the site includes a description of the first media coverage of the historic flight and an interview with th
Maps That Teach: US and World Geography
Created by Owl and Mouse Educational Software, this resource uses interactive maps to teach geography. The site provides both Map Puzzles and Interactive Maps. Map Puzzles are downloadable and must be run on Windows. They challenge users to piece together the States of the United States or the countries of the world's continents, depending on the puzzle used. Interactive Maps allow users to move their cursor over a basic regional map. As the cursor hits each country, its name appears. The page a
Datasheet Locator
With so many electronic components on the market today, it is often difficult to find datasheets with specifications and properties for a particular part. Rather than scouring the Internet for manufacturer's Web sites, Datasheet Locator has links to all the information you will need in one centralized location. The list of manufacturers currently numbers over 700. By directly connecting to the manufacturer's Web site, the information will always be up-to-date. Many of the companies allow searchi
FunBrain.com Kids Center
Seventeen fun, Web-based educational games are on Funbrain.com's Numbers site. The games cover basic arithmetic, fractions, graphs, algebra, and many other topics.
