The Why Files, created and based at the University of Wisconsin-Madison with funding support from the National Science Foundation, will be a boon to any science teacher. Each week the site publishes a new story that digs into "the science behind the news," providing readers with an erudite overview of the scientific issues that shape our world. Recent topics have included information about possible breakthroughs in the quest for an effective male contraceptive, how warming seas are affecting the cod population, and an expose on "flying" plankton. Educators searching for ways to enrich their lesson plans will want to scout the Archives, which go all the way back to 1999 and cover such topic as Arts & Humanities, Biology, Earth & Space, Environment, Health, and others. Additionally, the Teaching tab is loaded with helpful material, including suggested Why Files that meet the National Science Education Standards and Classroom Activities (discussion questions, quizzes, etc.) on popular topics ranging from tsunamis to the flu vaccine.
