In Middle School science, girls explore topics in life, earth, physical, and environmental science each year. The spiraling curriculum builds on concepts and skills at increasingly complex levels as girls progress through the Middle School. Inquiry-based, hands-on activities foster students’ critical thinking and problem-solving skills. Collaborative small group experiences that develop engineering skills are embedded into units at each grade level. Students design investigations, collect and organize data, analyze information, and draw conclusions from investigation results. They experience the scientific method in action when they design and carry out their own consumer product investigations. Following a study of Newton’s laws of motion, students construct and test their own roller coasters. Trips to local natural areas provide opportunities for students to apply classroom learning and cultivate an environmental stewardship ethic. Competition electives including PJAS, Future City, and PRSEF engage the students in further opportunities to delve deeply into current topics through both independent and collaborative work.
