The introductory session of the course begins with participants sharing and discussing their ideas about learning and where learning takes place. The participants then experience different inquiry-based, hands-on activities, as examples of the kinds of activities they will present on the floor of the informal science setting later in the course. A short presentation on what constitutes “learning in informal environments” provides the participants with a context for the next 10–15 weeks of the course and presents an overview of learning in informal science education institutions (ISEI) and their important role in helping people learn science content and practices. The goals, syllabus and requirements of the course are reviewed. The rationale for teaching ocean science, including its interdisciplinary nature, is discussed with an overview of the science content that will be covered in the course, kicked-off by an introduction to ocean biomes. The session concludes with a discussion about the homework.
