Produced by Dr. Leif Saul, a biology teacher and Web site/ game developer, Biology in Motion has two new interactive education activities. Organize-It introduces an alternative way to test biological understanding by organizing concepts hierarchically. This exercise intends to "remedy some of the shortcomings of the traditional multiple-choice quiz." Users can choose self-tests from a variety of biology topics. Evolution Lab allows users to investigate how natural selection works by watching an animated simulation. Both activities are interesting and effective learning tools. While the Flash features may seem geared toward kids, the content and language are really meant for older students. Helpful tips for using this Web site's activities in the classroom are provided. This site is worth a visit even for those not searching for teaching material. This site is also reviewed in the September 20, 2002 Scout Report.
