Science Department Philosophy

The Justin-Siena Science Department provides personal and collaborative instruction to facilitate the development in all students skills of observation, inquiry, experimentation, research, interpretation of data, critical reasoning, problem-solving, and effective communication of results in written, verbal, and graphical mediums.  Students move well beyond rote memorization to engage in regular hands-on lab work and application of concepts, and to gain confidence in their reading and writing across scientific fields.  Subsequently, students are well-prepared for college-level study of science, as well as lifelong appreciation of the importance of science in serving our society and global community.


Justin-Siena Graduation Requirement: Three years required
UC/CSU Admissions Requirement: Two years required; three years recommended
