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

Science Sampler : Rockin' around the rock cycle
The following inquiry-based activities were designed as part of a unit intended to aid students in understanding the rock cycle, with the assumption that, after being taught the lessons in the unit, students would have gone beyond a rote memorization of the rock types and rock cycle. The ultimate goal of this hands-on lesson is that students will know and be able to discriminate between them.
