Created and maintained by the fine folks at the University of California-San Francisco, the Science & Health Education Partnership (SEP) Lessons deserve to be well known by all science educators. The SEP was started in 1987, and represents a novel partnership between the university and the San Francisco Unified School District. The resources here are intended for use by K-12 students, but many of them can also be used in introductory college courses. First-time visitors should browse the About area and then move on to the Active Learning Lesson Plan Database. Here they can look for materials listed by grade level, subject, and type. To get a flavor for the materials here, visitors can look through the Recently Viewed area. Here they might find thoughtful lesson plans like "What factors affect the oxidation of apples?" and "Understanding Air Pressure." Finally, interested educators can reach out to the project leaders to learn about submitting their own lesson plans and materials for possible inclusion here.
