iLearn Technology recently posted a well-rounded list of online resources for teaching elementary students about habitats. Click HERE to see the original post and all 13 resources.
Draw That Habitat! from the very funny PBS show Fetch with Ruff Ruffman is one of the resources mentioned. Students are challenged to design a habitat that would meet the needs of an assigned animal. All of the drawing tools are embedded in the interactive and students can print their final creation.
Lots of great tools to check out here.
