Designed primarily for educators, this paper focuses on the importance of water in the daily life of all living creatures and on the role marine and aquatic education plays in helping individuals understand this concept. Section one discusses the limitations of water, human impact on the global water system, and the need to protect it. Section two emphasizes the broad scope and interdisciplinary nature of marine and aquatic education and presents a definition and set of objectives with their implications. Section three explains how marine and aquatic education fits into the goals of environmental education and general education and how it can be incorporated into the existing curriculum by using an example approach, activity approach, multidisciplinary approach, or course. The final section suggests people, places, and materials which could provide resource information and assistance to Ohio educators and others. The three appendices elaborate upon this information.
