About Earthbridges and Earthcast

The Earthbridges Community is happy to report that Earthcast, which is a live, global webcast that will take place on April 22. Earthcast16 was our ninth year in a row that the Earthbridges community was involved in the production of this event and we hope to build upon our successes of the past in many ways. During previous Earthcasts, we had contributions from people on different continents broadcasting in several different languages. We hope to have even more participation from more people around the globe during the upcoming Earthcast. Additional information is available on the Earthcast wikispace. Keep checking back for updates and to view the schedule to plan how you and your students can participate in this exciting event. Thank you for your support!

Earthbridges is part of the Worldbridges Community.
