Awakening minds like
no other science curriculum.

America’s most  awarded, most adopted science program.


Focuses on a student-first approach to teaching


Meets NGSS and state standards with a strong legacy of success


Transforms science class by providing unmatched support for educators

No one has brought active science learning to more classrooms than FOSS.

FOSS has raised standardized test scores, won numerous awards, and proven effective for students and teachers nationwide on a scale unrivaled by any competitor.




Makes students active investigators, not passive spectators.

FOSS is built around firsthand exploration of phenomena, using classroom-proven theories and practices to engage all your students.

The opportunity every
child deserves.

FOSS was designed from its roots to provide every child with the opportunity to develop their ability to think scientifically. The FOSS staff at the Lawrence Hall of Science devised FOSS to fully integrate active investigation and multisensory learning, an approach proven effective for all learners, regardless of prior knowledge, language, or background. If you, too, believe that every student can benefit in life from a solid scientific education and all that comes with it, your students deserve the advantages of FOSS.

“In the Oakland Unified School District, we evaluated middle school science instructional materials based on six criteria (led by) NGSS Alignment … and Common Core Connections. Our teachers and students rated FOSS Next Generation highest in every single category.”

-Brenda Tuohy, STEM Director, Oakland USD, California
