Journey North, an Annenberg Media "Learner Online" science education program, uses the Internet to track migration and signs of spring. Each year, students and teachers across North America go online (beginning on Groundhog's Day), to share their observations of the changing seasons. Targeting K-12 and high school students, the colorful homepage offers several interactive features -- from student or teacher discussion lists to the information-rich section Spring 1999. To get oriented, begin at How to use Journey North and click on the Orientation link. Then, select among several options. The Migrations project provides updated locations of a dozen birds and animals, from Bald Eagles to Hummingbirds, Manatees to Monarch butterflies, and Whooping Cranes to Whales. The Journey North News Calendar provides participants with an overview of upcoming information for focal species. And Signs of Spring uses indices like ice-out, leaf-out, and frogs to track the season's progress. This site could serve as a wonderful virtual lab for teachers seeking ways to integrate local classroom activities with global processes.
