This article describes an elementary science summer day camp at East Palatine High School in East Palestine, Ohio, for students in grades K-4, aided by high school (grades 9-12) student mentors. The school's Outdoor Area for Studies in Science (OASIS) is used for formal and informal studies in science for an elementary science camp week. The camp allows participants to make connections to the natural world and piques their interest in learning science. The high school students act as camp mentors, engaging in planning and implementation, while elementary students learn basic science from their older peers. Meanwhile, teachers watch the magic of learning science take place for all involved. The article provides details on planning for the science camp, science camp agendas and activities, the evaluation of the science camp, and recommendations for starting a science camp.
