About Electronic Magnetometers and Tobacco Smoking
Rating

This web page, authored and curated by David P. Stern, provides a non-mathematical introduction to modern magnetometers that depend on the saturation of magnetic materials. Applications include the observation the very weak magnetic fields in space and a 1979 experiment on the effects of cigarette smoking and the damage caused by asbestos. This is part of the site "The Great Magnet, the Earth". Also available in Spanish, German and French.

ActionBioscience
Rating

There are many websites dedicated to providing the public with information about the biological sciences, but ActionBioScience.org may be one of the best around. Started in 2000 by a group of concerned scientists and educators, the site provides articles by scientists, science educators and students on issues related to seven primary areas, including genomics, biotechnology, evolution, and biodiversity. All of the pieces on the site go through a peer-review process and are written with a keen eye towards providing information in a way that is largely jargon-free and highly accessible. From the homepage, visitors can look for articles in one of seven thematic areas, look for materials in Spanish, and peruse materials created just for educators. The site can also be browsed topically in the larger categories of Biodiversity, Environment, Genomics, Biotechnology, Evolution, and New Frontiers or from the "topic directory" which alphabetically lists all the bioscience subjects covered on the site.

African Arts
Rating

In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth. Learners first make cassava gel, then paint decorative symbols on cloth, and finally dye it. Learners examine the significance of symbols in African culture and communication, and the use of natural plant products for human projects.

Created and maintained by the Ahlul Bayt Digital Islamic Library Project (DILP), this nice website is designed to facilitate access to high-quality resources related to Islamic history, law, practice, and the societies of various Muslim peoples. The homepage is well designed, as it provides a general search engine, and an option to browse the site and its materials in four different languages. For those unfamiliar with the subject, they may want to begin by perusing the materials in the "Discover Islam" section. Here they will find essays that introduce the basic tenets of Islam and Muslim practices. The homepage also contains a list of the "Most Popular" areas of the site, which include a fine gallery of photos and calligraphy, along with a Shi'ite encyclopedia.

Algebra Balance Scales
Conditions of Use:
Read the Fine Print
Rating

This online manipulative features a virtual balance scale. It offers students an experimental way to learn about solving linear equations involving negative or positive numbers. The applet presents an equation for the student to illustrate by balancing the scale using blue blocks for positive units and variables and red balloons for negative units and variables. The student then works with the arithmetic operations to solve the equation. A record of the steps taken by the student is shown on the screen and on the scale. The applet reinforces the idea that what is done to one side of an equation must be done to the other side to maintain balance. Instructions for using the applet, background information about solving equations, and teaching suggestions are included.

Algebra Balance Scales
Conditions of Use:
Read the Fine Print
Rating

This virtual manipulative allows a teacher or student to represent a linear equation and solve it through the use of a balance beam. Unit blocks (representing 1s) and x-boxes (representing the unknown), are placed on the pans of a balance beam. Once the beam balances to represent the given linear equation, the learner can choose to perform any arithmetic operation to both sides of the equation keeping the beam balanced. The goal, of course, is to get a single X-box on one side, with however many unit blocks needed for balance thus giving the value of x. There is also the option of creating your own equations to solve.

Alike and Different
Rating

This activity (on pages 7-13) has pairs of learners survey an array of similarities and differences between them. The differences survey worksheet focuses on genetically inherited physical features, such as hair color, eye color, ear shape, and tongue folding and rolling. By tallying the whole group's features, they will consider which features are "dominant" (occurring more often). The activity includes reflection questions to encourage writing.

American Planning Association
Rating

The discipline and practice of planning includes physical design, economic development, and a myriad of other specialties. The American Planning Association (APA) is perhaps the best known organization in the United States, and their website contains some very fine resources for those already in the field as well as for those who would like to join the field. On the site's homepage, visitors can learn about upcoming conferences and workshops, learn about joining the APA, and also read recent news updates about various aspects of planning. While not all of the materials are available to non-members, visitors should definitely look over the APA Advocate, which is their bi-weekly newsletter that addresses legislative and policy issues that directly affect planning. Perhaps one of the best general-purpose areas of the site is the "Your Community" section. Here, visitors can learn about their "Green Communities" initiative, view a set of resources designed to teach children about planning, and read about National Community Planning Month.

Maintained by the Population Reference Bureau (see the November 17, 1999 Scout Report for the Social Sciences, AmeriStat provides "instant summaries -- in graphics and text -- of the demographic characteristics of the U.S. population." These demographic snapshots can be customized by the user and provide statistics on such topics as population estimates and projections, marriage and family, education, race and ethnicity, income and poverty, migration, fertility, children, foreign-born population, older population, and more. The different sections offer relevant links to US Census data, and the site provides a link to the Population Reference Bureau. Demographers at the University of Michigan and SUNY - Albany also contribute to the site.
