Mark Friedman presented the workshop “Teach Marine Biology in Lieu of Biology” at the 2010 National Association of Biology Teachers conference in Minneapolis. This comprehensive biology course for high school students focuses on marine life and covers all California State Biology Standards. Developed by Los Angeles area high school teachers who currently teach Biology and Marine Biology with support from COSEE-West, online and sample materials (lesson plans, labs, activities, games, puzzles, web interactives, movies with thought questions, web quests, etc. with many resources available in Spanish for ELL) were introduced. The workshop also introduced educators to the new C-DEBI project including the “Adopt a Microbe” effort, the ability to SKYPE the Joides Resolution from classrooms, and the forthcoming materials like lesson plans and activities that will be developed by teachers and students associated with C-DEBI.
