Earth Odyssey is an outreach program for grades four to six developed by a Los Angeles museum. Museum instructors work with classrooms over the course of one month to conduct field observations of living things in the schoolyard and in a local park. Students then compare the rates of biodiversity observed in both areas. The goal of Earth Odyssey is not to fill students’ heads with specific information about plant and animal species, but to teach them the techniques used by scientists in the field and let the students do the rest.
