Field Study & Discovery Trips All students at The Rhoades School participate in field study and/or discovery trips. In grades K-3, students may take day trips to explore a California mission or an interactive aquarium. Fourth grade students take an overnight trip to Riley's Farm to participate in American Revolution reenactments. As a culminating lower school academic and character building experience, fifth grade students spend a week exploring Native American historic sites in Arizona and New Mexico. Middle school students spend several days to a week at Astro Camp (a hands-on physical science program with an emphasis on astronomy, space exploration and character building), Catalina Island Marine Institute (marine science field study) and Washington D.C.
