As the name implies, the colorfully animated Switcheroo Zoo -- produced by Tubehead, an interactive multimedia studio -- allows you to swap the heads, legs, or tails of various zoo animals to create fantastical new creatures. Not just a place to watch cool morphing animation, this Web site has educational applications as well. Click on Educators' Resources, and scroll to the bottom of the page for a simple lesson plan geared toward younger students. The lesson plan is designed to "expand students' knowledge of animals and develop critical thinking skills," and "engage students in the creative application of that knowledge, as information about the characteristics of animals and their habitats is used to describe imaginary creatures." Useful links for researching the animals are provided on the same page, as are links to other education-oriented sites. By September 2002, users should find Switcheroo Zoo 50% faster with dozens of new animals.
