Overview of the SFUSD High School Science Curriculum
The San Francisco Unified School District (SFUSD) high school science curriculum is designed to provide every student with a rigorous, coherent pathway to scientific literacy. Built around the Next Generation Science Standards (NGSS), the program emphasizes inquiry, critical thinking, and real-world application. Rather than memorizing isolated facts, students engage with phenomena, design investigations, and develop evidence-based explanations that mirror the work of scientists and engineers.
This curriculum is structured to support college and career readiness for all learners. It aligns course sequences with state graduation and university entrance requirements, while centering equity and access. Students experience a blend of core science disciplines over multiple years, giving them repeated opportunities to build and deepen their conceptual understanding.
NGSS-Aligned Course Pathways in High School Science
High school science in SFUSD is organized into a series of courses that integrate core disciplinary ideas with science and engineering practices and crosscutting concepts. The pathways are carefully sequenced so that students revisit major ideas at increasing levels of sophistication throughout their four years of high school.
Three-Dimensional Learning
The NGSS model used in SFUSD emphasizes three dimensions of learning:
- Disciplinary Core Ideas (DCIs): Key concepts in physical sciences, life sciences, Earth and space sciences, and engineering.
- Science and Engineering Practices (SEPs): Skills such as asking questions, developing models, analyzing data, and constructing explanations.
- Crosscutting Concepts (CCCs): Big ideas—like patterns, cause and effect, and systems—that connect learning across topics and disciplines.
Each course in the sequence blends these three dimensions, encouraging students to think like scientists and engineers as they explore complex phenomena and problems.
Core High School Science Courses
The SFUSD high school curriculum typically begins with integrated science courses that lay a broad foundation, followed by increasingly specialized options. While exact offerings can vary by school, the core progression is designed to ensure that every student gains experience across multiple domains of science.
NGSS Integrated Science Courses
Integrated science courses bring together ideas from life science, physical science, and Earth and space science into cohesive units driven by real-world phenomena. Instead of studying biology or physics in isolation, students encounter topics that draw on several domains at once, mirroring the interconnected nature of scientific challenges.
Through these courses, students may explore questions such as how climate systems work, how energy flows through ecosystems and human communities, or how forces shape both planetary motion and everyday technologies. Engineering design challenges are woven into each unit so that students apply core ideas to practical problems.
Biology as a Foundational Life Science
Biology remains a central component of the high school science experience. SFUSD's biology expectations go beyond recalling cell parts or stages of mitosis. Students investigate phenomena like inheritance patterns in populations, ecosystem changes, or the impacts of human activity on biodiversity. They use models to understand molecular mechanisms, analyze data from authentic or simulated investigations, and construct arguments supported by evidence.
Chemistry and the Structure of Matter
Chemistry courses deepen students' understanding of the structure and properties of matter, chemical reactions, and energy transformations. In an NGSS-aligned context, students explore how particle-level interactions explain macroscopic behavior, such as phase changes, reaction rates, or material properties. The curriculum emphasizes lab-based inquiry, quantitative reasoning, and scientific communication, so learners can connect abstract theories to empirical evidence.
Physics and the Laws Governing Motion and Energy
Physics offerings focus on motion, forces, energy, waves, and, in some cases, electricity and magnetism. Students formulate and test models using mathematics, data collection, and computational tools. The curriculum highlights everyday applications—from transportation and engineering to sound, light, and modern communication technologies—helping students see physics as a powerful lens for understanding the world.
Advanced and Specialized Science Options
As students progress through their high school careers, the SFUSD science curriculum includes opportunities to pursue more advanced or specialized study. These options are intended to support diverse interests and future pathways in STEM fields while maintaining inclusive access.
Honors and Advanced Courses
Honors and advanced-level classes allow students who are ready for greater depth and pace to engage with more complex content and sophisticated investigations. These courses emphasize independent inquiry, extended projects, and analytical thinking, creating strong preparation for college-level science and STEM majors.
Electives and Interdisciplinary Science
Some schools offer electives that connect science with other disciplines or emerging fields, such as environmental science, biotechnology, or engineering-focused courses. These classes give students a chance to explore interests that may relate directly to local community issues, regional industries, or global challenges.
Equity, Access, and Inclusive Science Instruction
The SFUSD high school science curriculum is guided by a commitment to equitable access. All students, regardless of background or prior experience, are expected and supported to engage in challenging scientific work. Instructional materials and strategies reflect diverse perspectives, highlight contributions from scientists of many cultures, and address real issues affecting students' communities.
Classroom practices emphasize collaboration, multiple ways of showing understanding, and language supports for multilingual learners. Teachers use formative assessment to identify students' ideas and build on them, rather than treating misconceptions as deficits. This approach helps create a learning environment where students see themselves as capable contributors to scientific conversations.
Science and Engineering Practices in Everyday Learning
Across all high school science courses, students repeatedly engage in the core practices of science and engineering. Instead of following step-by-step lab instructions, they are asked to design investigations, justify their methods, and interpret findings. They critique and revise models, analyze data sets, and communicate their reasoning using evidence and disciplinary language.
This emphasis on practice helps students develop transferable skills: critical thinking, problem-solving, collaboration, and clear communication. These abilities matter not only in STEM careers but also in civic life, where evaluating evidence and reasoning through complex issues are essential.
Assessment Aligned with Deeper Understanding
Assessment within the SFUSD high school science curriculum is designed to capture what students can explain and do, not just what they can recall. Performance-based tasks, written explanations, and collaborative projects are used alongside more traditional quizzes and tests. Students are often asked to make sense of new phenomena, apply models to novel contexts, or use data to support or refute claims.
This approach to assessment reinforces the idea that learning science is about building and refining ideas over time. Feedback focuses on progress toward proficiency in the NGSS performance expectations, giving students clear insight into their strengths and next steps.
Preparing Students for College, Careers, and Civic Engagement
The ultimate goal of the SFUSD high school science curriculum is to prepare students for life beyond graduation. Whether students continue into four-year universities, community colleges, technical training, or the workforce, they need a strong foundation in scientific thinking and literacy.
By engaging with authentic, relevant phenomena and problems, students gain insight into potential STEM careers and how science influences decisions in health, environment, technology, and public policy. They learn to weigh evidence, consider trade-offs, and communicate reasoned arguments—skills that are vital for informed participation in a rapidly changing world.
Connecting Classroom Science to the Wider Community
A notable strength of the SFUSD approach to high school science is its emphasis on real-world connections. Teachers and curriculum designers integrate local environmental issues, community partnerships, and culturally relevant examples to make learning meaningful. Students might investigate local air quality, study regional ecosystems, or explore how technological innovations shape life in their city.
These experiences help students see that science is not confined to textbooks or labs but is woven into daily life and community decision-making. They come to understand that their scientific knowledge and skills have the power to influence real outcomes, both locally and globally.
