From molecules to mountains.
From molecules to mountains.
The primary goal of the Science Department is to provide you with a foundation of scientific literacy necessary to play an informed and intelligent role in our modern technological society. The department offers a wide spectrum of required and elective courses so that, through exposure to both physical and life sciences, you will be introduced to the problem-solving skills, concrete and abstract ideas and laboratory techniques that encourage an understanding of science.
In the Science Department, learning takes place both in the classroom and in the field. You use the fully equipped science labs for a variety of investigations and take advantage of computers to collect and process data efficiently. Classes head outdoors to study the local creeks, chaparral, and nearby tide pools. If you’d like to pursue a topic in greater depth you can work individually with a faculty member or a professional scientist on a science research project. In recent years, students have designed projects in molecular genetics, nutritional research, and biochemistry.
Year course. Physics is an algebra-based physics course designed for freshmen. Students investigate the traditional concepts of motion, force, work, energy, waves, sound, and electricity, in preparation for chemistry. Instructional methods follow a research-based guided-inquiry model that capitalizes on hands-on, cooperative learning where students construct their knowledge and find answers to their questions as they investigate and practice scientific inquiry in the laboratory. Students demonstrate their knowledge and are evaluated using traditional assessments, scientific journaling, and performance assessments. The course emphasizes finding and describing patterns in nature, depth over breadth of material, fostering and leveraging disciplined curiosity, and sharpening scientific inquiry practices. Students should leave the course with a firm conceptual understanding of physics and the nature of science. In addition, students they will leave with many skills including, but not limited to, scientific inquiry practices, lab set up and design, and data collection and analysis using digital probes and software.
Year course. Physics with Trigonometry is the foundational science class for incoming freshmen at Cate with an advanced mathematical background. Students will construct an understanding of how things move (kinematics) and why things move (dynamics) as they conduct laboratory investigations and build conceptual and mathematical models. Students will also explore the great conservation laws, those of momentum and energy, as they deepen their understanding of the physical world. Finally, students will examine wave phenomena, from oceans to earthquakes, as a manifestation of the movement of energy. Throughout, students will develop their skills in inquiry as they ask and answer questions while conducting hands-on, collaborative investigations. Students will learn to approach problems through and as an extension of their deep conceptual understanding. Upon completion, students will be well-prepared to continue the application of scientific inquiry practices, digital data collection, organization, and analysis to chemistry, biology, and the rest of the Cate science curriculum.
