The SPS Science Program is inquiry based and enforces the scientific method where students are able to expand scientific knowledge and skills through individual and cooperative group experiments and projects.

One of Saint Paul School's goals is to provide students with "hands-on" activities and relate concepts to real-life scenarios. This is met through the addition of Science Lab in grades 3-8. The lab teacher's role is to work in conjunction with classroom science teachers in grades 3-8 to enhance the science curriculum with experiments that provide students with opportunities to apply concepts learned.

The Science Fair is attended by school families. Students in grades 5-8 exhibit their work through verbal and visual presentations, highlighting their findings using the scientific method. The recent addition of a WeatherBug weather station provides SPS students with on-site weather data, along with interactive lessons using the WeatherBug Achieve web-based software. Field trips and on-site visitations supplement the science curriculum. The Rutgers Science Bus visit gives students in grades 6-8 the unique opportunity to perform experiments with laboratory scientists from Rutgers University that coincide with a particular topic in their curriculum. Experiments dealing with Matter, Marine Ecology, DNA/Genetics, Petroleum and Oil Exploration, Anthropology, and Micro-Biology are presented at grade level, relating concepts to current practices and theories. Princeton University has also afforded our students the opportunity to visit and work with their scientists.

Field trips that stress social responsibilities in ecology teach SPS students their role in maintaining a safe living environment. For example, a recent trip to the Stony Brook Watershed showed students where water is gathered for human consumption and the delicate balance in nature that must be maintained to ensure water is not contaminated. Students learned what practices they could use to help keep the environment healthy. This very important curricular component helps SPS fulfill its school mission to provide sound spiritual, moral/ethical, and social teachings where students learn to cultivate respect for all, promoting fairness, tolerance, accountability, and compassion in the treatment of others in their daily lives.

The Scientific Method is a vehicle for the acquisition and application of essential life skills. Students learn to ask questions, do research, hypothesize, test, analyze, and reach conclusions. The experiences and activities provided through the enhanced science curriculum will enable students to assume a value-centered role in a global society.
