From Annenberg Media, this website shares Bottle Biology construction methods and learning activities with K-6 educators. Bottle Biology is an experiential-based learning technique that was originally developed by Paul Williams, a professor of Plant Pathology at University of Wisconsin-Madison. Bottle Biology utilizes "recyclable containers as building blocks that can be put together to form any number of bottle systems to explore science, nature, and the environment." This site offers four Bottle Biology systems, each developed as companions for sessions in a larger Life Science Course "designed to provide teachers with learning opportunities that will directly inform their own classroom practice." The Course Sessions are coupled with free instructional videos (registration required), and presented with suggested hands-on activities. The first Bottle system is designed to reinforce concepts regarding the classification of living things and definitions of life; the second addresses the interconnection of animal and plant life cycles; the third focuses on evolution, and the fourth explores interdependence. This site is also reviewed in the October 29, 2004 _NSDL Life Sciences Report_.
