Eco-Inquiry, an ecology curriculum for grades 5-8 developed by Dr. Kathleen Hogan, a former Associate Scientist, helps teachers transform their classrooms into centers of ecological research. Students learn about the flow of matter in ecosystems as the practices of science are demystified and made engaging. Over 5,000 copies of the 400-page teacher's guide have been sold. For a copy, contact the publisher, Kendall/Hunt Publishing Company ($34.95 plus shipping, call: 800-228-0810). Two Eco-Inquiry supplements also are available from Kendall/Hunt: Rita - a book for children, and Promoting Student Thinking - A Teachers' Guide to Linking Science and Literature Through Rita.
