This Web site is the online companion to the recent PBS NATURE documentary "Horse and Rider," which "explores a fascinating partnership between animal and human." Click on For Teachers on the main Web page to find an interdisciplinary lesson plan for grades 9-12. The lesson, titled Creating the "Perfect" Horse, has students study horse biology and behavior, explore the reasons why different horse breeds were developed, and analyze research findings to determine if breeding an all-purpose horse is practical or even possible. The lesson plan provides downloadable worksheets, and the main Web page contains some fun special features, including video clips. This site is also reviewed in the September 19, 2003 NSDL Life Sciences Report.
