FOSS®: The science curriculum that puts students first.

Every student deserves the benefits of science education—not just exposure to scientific phenomena, but the opportunity to understand and explain them. FOSS is the K–8 science program proven to afford that opportunity to all, regardless of background, culture, language, or ability. In FOSS, students don't just read about scientific concepts. They actively investigate them, taking on the roles of scientists and engineers. See what develops when students step away from their screens and start exploring scientific phenomena firsthand. Try FOSS with your own students and teachers, free.

The most awarded, most adopted science education program.

Classroom-proven, research-based FOSS has amassed a legacy of successful implementation unrivaled by any other elementary and middle school science curriculum.

FOSS doesn't just meet the standards, it embodies them.

Today, the Next Generation Science Standards (NGSS) call for students to not just remember answers to questions, but to ask the questions, analyze and interpret data, and solve problems. For three decades, the FOSS Development Team at UC Berkeley's Lawrence Hall of Science has built FOSS® around these goals. FOSS provides engaging firsthand experiences that focus on three-dimensional learning dimensional learning and build in a sequence that delivers on NGSS performance expectations.
