Content Clips is a free, interactive web environment that features compelling online resources for K-12 teachers, including images, sounds, and video clips to help build student understanding of science concepts and the natural world. It offers easy-to-use tools (no programming required), a growing multimedia collection, an “add-your-own-clip” feature, and a simple way to combine and arrange online content from multiple sources into customized presentations or learning activities. The interactive fossil sort, used as part of an assessment probe activity and the electronic storybooks in the most recent issue of the Beyond Penguins and Polar Bears magazine, illustrate how teachers can use Content Clips to create their own classroom interactives. Note that Content Clips requires Adobe Flash.
