Home > Departments > Science Courses
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.

Physics introduces all Cate ninth-grade students to scientific inquiry and problem-solving. After framing science as a “way of knowing,” students explore fundamental mechanics topics of kinematics, projectile motion, statics, dynamics, momentum, and energy along with wave phenomena of light and sound. Students focus on exercising scientific practices: asking scientific questions and defining problems, planning and carrying out investigations, developing and using models, analyzing and interpreting data, using mathematics and computational thinking, arguing from evidence, and communicating in both verbal and written forms. Students are expected to extract the majority of their learning from these experiences and from each other with teachers serving as guides and coaches. With these scientific and metacognitive tools, Cate ninth-grade students leave the course with a firm conceptual understanding of physics and the nature of science in preparation for Chemistry and Biology at Cate. Instructional methods follow a guided-inquiry approach where students are expected to do science — collaboratively explore phenomena, seek answers and solutions, find patterns, and develop and use models to predict the future. Required for all ninth-grade students at Cate.
