Wired: New Browsers, Same Unwanted Ads
This article from Wired News reports on current trends in spyware and adware. The author discusses how people who stopped using Internet Explorer and started using alternate browsers, such as Mozilla Firefox, to avoid advertisements and improve internet security, may find that "spyware and adware writers are also making the switch." The author argues that as Mozilla gains more users, writers of spyware and adware programs will start writing for those browsers as well. On the positive side, the a

Observe one place at many scales
Developed for high school students, this Earth science resource utilizes a set of six enlargeable images to illustrate the meaning of map scale. Introductory text explains that because of the incremental changes in scale, the details in each image appear ten times larger than in the prior image. The first image in the set was taken at a scale that shows the globe, and the final image shows a city block in Atlanta, Georgia. There is an animation below the images that begins with the global view a

Quick take on exploring careers in mathematics
Even though the potential connection between today s math classroom and the jobs of the future is frequently cited in speeches, reports, and news headlines, busy middle school students may not be paying attention. Here are five online resources that can help you make the connection more relevant, and a lot more engaging, to preteens. In some cases, the connection appears in the words of young people who recognize that math and science were the keys to jobs they love.

Function machine (grades 6-8)
Applying a machine metaphor for functions, this virtual manipulative allows the learner to examine the relationship between input (domain) and output (range). The learner inputs numbers from one to four and the virtual machine generates output information in a table. The learner is challenged to find the output for values five through seven and enter them in the table. Errors are noted automatically. Using a new function button, different types of functions are randomly offered for investigation
