The Lower School science curriculum focuses on an integrated study including the three major disciplines: life, earth, and physical. The Science Department adheres to the inquiry method of teaching, and therefore, hands-on activities are incorporated into all lessons as deemed appropriate.

While the curriculum for each level is similar in framework, each grade builds upon what was learned the previous year. Additionally, current topics in science are introduced as they relate to the curriculum or current events. In developing useful scientific skills and knowledge, the curriculum introduces simple classroom and field investigations. Students identify the components of the natural world including rocks, soil, and natural resources. In addition, students identify and explore living organisms.

Lower School science is taught by grade level teachers and hands-on activities are encouraged in order to clarify and solidify the content of the lesson. The goal of each teacher is to help students better understand the importance of relationships that exist between living and nonliving components of the world. This knowledge enables students to make environmentally sound decisions based on their expanded knowledge of the world in which they live.

Students in Lower School visit the Alice and Erle Nye Family Environmental Science Center once every six weeks. A comprehensive scope and sequence has been developed for the Environmental Science Center for students in kindergarten through eighth grade. The science curriculum for each grade is thematic and concepts introduced are built upon from one year to the next.
