Life on the Tidal Mudflats: Elkhorn Slough.

Life in an estuarine environment is studied in this set of audio-visual materials prepared for grades 6-12. A 71-frame colored filmstrip, cassette tape narration, and teacher's guide focus upon Elkhorn Slough, a tidal mudflat in the Monterey Bay area, California. Topics examined range from river drainage and the effects of pollution on living organisms to the characteristics of transition from dry land to wet marine world. The teacher's guide reproduces line drawings of all the filmstrip frames, the complete text of narration, supplementary information for each frame, a glossary of terms, and a bibliography. It is suggested this set of materials be used in ecology, biology, marine science, oceanology, and environmental studies. (BL)
