Worldwide Ocean Optics Database
http://wood.jhuapl.edu/
Created and maintained at the Johns Hopkins University Applied Physics Laboratory, the Worldwide Ocean Optics Database (WOOD) contains several hundred datasets, gathered over time from much of the world's oceans, specifically on optics. The data can be searched via an applet or a text-based query system that includes parameters such as date, depth, salinity, upwelling radiance, turbidity, secchi depth, and many more. The site provides several downloadable software programs that allow users to further utilize the data at their convenience and a link that offers information on how to decipher the specific codes used in the datasets. Even though a few links occasionally did not work correctly and users will need a little time to familiarize themselves with the database, the site does provide those working in related field access to valuable information.

Droplet and the Water Cycle [Flash]
http://kids.mtpe.hq.nasa.gov/droplet.html
From NASA's For Kids Only Earth Science Enterprise Web site comes the interactive learning game, Droplet and the Water Cycle. Using Flash Macromedia, kids get to control an animated droplet of water falling from the sky in hopes of learning more about the water cycle. Controls are described on the first page, which allow you to move the droplet through a forest, a river, and an ocean while avoiding things, like butterflies and insects, which are very thirsty. The game can be downloaded to PC and Macintosh computers for free or played online. Although it is fun and challenging to play, it could use some more questions or other means of reinforcing the learning. [JAB]

Clouds
http://seaborg.nmu.edu/clouds/
Created by Carl Wozniak, Clouds attempts to make the study of clouds and the processes of cloud formation more accessible for elementary and early secondary classroom study. The site accomplishes this by breaking information down into five sections, complemented by both descriptive text and relevant pictures. Pictures and graphics are perhaps the most classroom-friendly section of the site, as they are intended for use in non-profit, educational settings. Another primary section of the site is the glossary, aimed at explaining cloud-related terminology at a very simplistic level, understandable by younger students. [LB]

Park Geology: Tour of National Parks
http://www2.nature.nps.gov/grd/tour/index.htm
A great site from the National Park Service, Geologic Resources Division provides information on geologic features of our national parks. The site is aimed at a young audience (K-8), but is a pleasure to browse for anyone. Organizing the site by geologic features (e.g., Hot Springs, Oldest Rocks, and Volcanoes) allows readers to compare the geology of various national parks and explore maps, photos and other related links.

AirJunk: Specks, Flecks and Particles in the Air
http://www.hhmi.org/coolscience/airjunk/index.html
This amusing, albeit small, virtual exhibition by the Boston Children's Museum and supported by the Howard Hughes Medical Institute (HHMI) examines the everyday science of dust. It is part of an online science series sponsored by HHMI called Cool Science for Curious Kids, with each exhibit developed by a different museum. The series introduces the science behind something children "already know." Among the participating museums are the Chicago Academy of Sciences, San Jose Children's Discovery Museum, the Scotia-Glenville Children's Museum, and the Minnesota Children's Museum. AirJunk helps children explore dust and its effect around the home by encouraging experimentation and observation. The brevity of this exhibition makes it appropriate only for young learners. In addition to the learning opportunities, this site has the funniest animated nose this reviewer has ever seen. [DJS]

TerraFly
http://www.terrafly.com/
Associated with the School of Computer Science at Florida International University, the High Performance Database Research Center (HPDRC) released TerraFly in November 2001, a Web-based application that allows users to view Geographic Information Systems (GIS) images. In agreement with TerraFly, the United States Geological Survey (USGS) provides the project with many of its satellite images in exchange for a public service: free Web-based access to its application. Through a rather sophisticated Java applet, users have a bird's eye view of the images, much like other Internet services have provided in the past, such as TerraServer (last mentioned in the June 28, 1998 Scout Report). TerraFly, though, improves the still picture delivery of these services by enabling users to view the images continuously and seamlessly, giving the user a feeling of "flying over" the photographed land areas. Different resolutions are available, and the interface is extremely slick though somewhat complicated initially. Users of low bandwidth or active memory should be wary; the applet demands a lot from your computer. Also, even though access to the Web-based application is free through the USGS agreement, users should be aware that the TerraFly Project seems to have mostly commercial motivations. (Note: This reviewer had difficulty using Terrafly with Mac Netscape 4.7. Mac Internet Explorer functioned properly.) This site is also reviewed in the April 5, 2002 Scout Report. [TS]

The Degree Confluence Project
http://www.confluence.org/
The goal of the Degree Confluence Project is to have an organized sampling of the world by visiting each of the latitude and longitude integer degree intersections in the world and take pictures at each location. Started by Alex Jarrett in February of 1996, there are currently 12,542 photographs taken by different people in 87 countries, along with narratives describing the adventures it took to get there. Visitors of the site can view the photographs and read the interesting stories, as well as learn how to find and take pictures of the degree confluence near them. [JAB]

Magnet Man: Cool Experiments with Magnets
http://www.execpc.com/~rhoadley/magindex.htm
Developed by magnet enthusiast Rick Hoadley, this site for middle and high school students is no-nonsense in style. The explanations and experiments on this page are designed around a series of increasingly more complex issues of magnetism from What is magnetism? to Build your own Gaussmeter (a device that measures the strength of a magnet). Each experiment is systematically written in clear terms with images for crucial steps. Mr. Hoadley even offers price estimates for each item needed to perform the experiment. To continue learning about magnetism, brief resource lists for additional Web resources and books on magnets are also offered. [DJS]

Eclipse Home Page
http://sunearth.gsfc.nasa.gov/eclipse/eclipse.html
Whatever else one might say about the subject, eclipses are events not to be missed. So, if you're tired of missing eclipses because you just aren't sure when they are going to occur, or where, you no longer have such an excuse, as this site lists all eclipses, lunar and solar, past and present, and their ideal viewing locations all over the planet. Sponsored and maintained by NASA's Goddard Space Flight Center, the site offers information for anyone interested in astrophysical events, especially planetary conjunctions. For each eclipse featured on the site, date and time are listed first, followed by additional facts and figures, including detailed charts of the course of planetary alignments that indicate, among other things, duration and magnitude of the event and the locations where it can best be viewed. Particularly worth visiting is the Seven Thousand Year Catalog of Very Long Eclipses. And, for those just starting out, there is a beginner's introduction to the study of eclipses. [WH]

Near Real Time Earthquake List
http://neic.usgs.gov/neis/bulletin/
The United States Geological Survey's National Earthquake Information Center site offers readers near real time updates of seismological events worldwide. As one can gather from a glimpse at the report, our planet is in a near constant state of geophysical change and upheaval, given the numerous earthquakes registered on a daily basis by the NEIC, sometimes up to a dozen or more. Readers will discover that the NEIC Web site lists, in chronological order, the earthquakes of the past several days, each with its own hyperlink to separate pages that detail geographic location and magnitude of specific events, as well as the faults responsible for geological upsets. Beyond the above, the site lists activity for the past week and month -- all with charts, maps, and detailed descriptions of regions cited. [WH]

Life, the Universe, and the Electron: An Exhibition to Celebrate the Centenary of the Discovery of the Electron [Quicktime, Shockwave]
http://www.sciencemuseum.org.uk/on-line/electron/index.asp
Although earlier scientists argued these tiny subatomic particles (with a mass later discovered to be 9*10-31 kg or 1 two thousandth of the mass of a proton) must exist, no objective proof had been offered. While conducting experiments on cathode rays, J. J. Thomson "showed that cathode rays were particles with a negative electric charge and much smaller than an atom." These early experiments laid the foundation for our understanding of the atom and the birth of electronics. The exhibition follows this chronology of our evolving understanding of atomic structure and explains briefly each discovery along the way. This exhibition delivers each episode in the history of nuclear physics in a clear, straightforward manner and supplements essays with short animations and clips. Produced to commemorate the 100th anniversary of the discovery of the electron in 1997, this virtual exhibition from the Science Museum (London) and the Institute of Physics remains a useful and attractive learning tool for high school students and learners of all ages.
