Update April 2014: This site appears to have gone offline. 

itv Wild is a great website for finding video clips and longer feature programs  about wildlife found all over the world. itv Wild is designed for elementary school age students to learn about the challenges facing wildlife around the world today. Visitors to itv Wild can browse the selection of clips and features or search by keyword. itv Wild offers a game for students to test their knowledge of the wildlife and habitats they learned about in the various videos and features they have watched.

Applications for Education
The videos on itv Wild could be useful for supporting an elementary school lesson about endangered wildlife and habitats. itv Wild does include a simple rating system to advise you as to whether or not a particular set of clips might be upsetting to young students (the set of Polar Bear videos has this warning). That could be very helpful in selecting appropriate clips for your students to watch.
