Welcome to BLS Science! 

The Boston Latin School Science Department is committed to excellence in science education. We enhance science education through technology, guided inquiry, hands on activities and experimentation. The BLS Science Department is divided into five disciplines: Earth Science, Biology, Chemistry, Physics and Environmental Science. Students follow a standard progression through introductory and upper level courses in these disciplines.
Class VI Earth Science

Class III Physics I or Chemistry I
Class II  Class I Elective choices: Environmental Science, Environmental Science AP, Biology II, Biology AP, Chemistry I, Chemistry AP, Physics I, or Physics AP

Every BLS student must take a total of three years of a science and all course include a laboratory component. Our faculty members each bring personal interests and expertise to their teaching. The department is guided by State, City and national standards. We are also involved in a number of collaborations and programs with outside organizations to enrich our students experience of science.
