Crazy about animals? Well I am and so are my kids. We just found this amazing documentary, In the Valley of Wolves from freetech4teachers.com (an excellent website by the way) . The website says "It is a documentary film about the Druid wolf pack in Yellowstone National Park. The film chronicles a three year span of the pack's expansion and subsequent decline in size. The film can be viewed in its entirety on PBS Video."
(Caution: Videos contain music so pls hit the mute button when music starts)
The website also offers interactive maps of the area, and lesson plans for elementary(primary, KS1, KS2) and high(secondary, Ks3,KS4) school use.
