This lesson is part of the, Our Wetlands, Our World High School Activity Guide to Upper Newport Bay developed by the California Coastal Commission and can be found on pages 70-74 of the pdf file. In this lesson, students compare aerial photographs of Upper Newport Bay taken in 1938, 1975, and 2001 to discover how the area has changed and what impact that change has had on the wildlife living there. Students identify changes in different areas of the photographs. Then, species cards, located in Appendix A, determine possible impacts on the wildlife in each area as a result of the changes. Students then use a timeline to relate historical events to the photographs.
The recommended time for this activity is 1 hour, although it may take longer.
