Prince William County Public Schools (PWCS) provides a comprehensive science program from kindergarten to grade 12. Instruction is aligned to the 2018 Virginia Department of Education Science Standards of Learning.

Students have an opportunity to:

Students demonstrate mastery of their learning on Virginia assessments in grades 5 and 8, and are required to earn a verified credit toward graduation by passing one high school "End-of Course" state science assessment.

Safety of the learning environment is our priority; all stakeholders are expected to adhere to the rules of the "PWCS Science Instructional Safety Agreements."

The PWCS Student Learning Department supports our students, teachers, and instructional leaders by:

  • Providing division-approved core and supplemental instructional materials
  • Developing pacing and unit guides for core science courses, and unit and benchmark assessments
  • Offering professional development on best evidence- and research-based practices
  • Supporting Virginia Meaningful Watershed Educational Experiences, PWCS Environmental Literacy Plan, Irene V. Hylton Planetarium at C.D. Hylton High School, and the observatory at Forest Park High School
  • Sponsoring the Prince William-Manassas Regional Science and Engineering Fair in partnership with Leidos and the I-66 Mobile Partners

IB Chemistry 2 (SL)

This second-level course provides students with a comprehensive hands-on study of major chemical principles emphasizing laboratory experiences and research. Students study research techniques,  advanced problem solving, and synthesis of prior knowledge to investigate IB option topics. Participation  in an interdisciplinary science research (Group 4) project is required. Laboratory investigations form a  major component of the course, and all students must maintain a portfolio of laboratory work that is  presented to the IB examiners. With a satisfactory IB exam score, students may receive credit for  introductory college chemistry. Students are required to take the IB Chemistry Standard Level Exam and  complete the required hours and assignments tied to the SL Chemistry Internal Assessment. Credits 1 Grades 11, 12

IB Environmental Systems and Societies (SL)

This one-year course provides students with a perspective on the interrelationships between ecosystems and societies. Students will emerge from the class with an understanding of complex environmental issues in which the interaction between ecosystems and societies is central. Sustainability is the integrative theme of this course. Students will develop the capability to formulate an informed personal response to both local and global issues.
