What Is FOSS?
FOSS is a research-based science curriculum for grades K8 developed at the Lawrence Hall of Science, University of California at Berkeley. FOSS is also an ongoing research project dedicated to improving the learning and teaching of science. The FOSS project began over 20 years ago during a time of growing concern that our nation was not providing young students with an adequate science education. The FOSS program materials are designed to meet the challenge of providing meaningful science education for all students in diverse American classrooms and to prepare them for life in the 21st century. Development of the FOSS program was, and continues to be, guided by advances in the understanding of how youngsters think and learn.
Science is an active enterprise, made active by our human capacity to think. Scientific knowledge advances when scientists observe objects and events, think about how they relate to what is known, test their ideas in logical ways, and generate explanations that integrate the new information into the established order. Thus the scientific enterprise is both what we know (content) and how we come to know it (process). The best way for students to appreciate the scientific enterprise, learn important scientific concepts, and develop the ability to think critically is to actively construct ideas through their own inquiries, investigations, and analyses. The FOSS program was created to engage students in these processes as they explore the natural world

Over the past 20 years, with the support of the National Science Foundation and the University of California at Berkeley, the FOSS program has evolved into a curriculum for all students and their teachers, grades K8. The current editions of FOSS (20002003) are the result of a rich collaboration between the FOSS/LHS development staff, the FOSS team at Delta Education, assessment specialists and educational researchers, dedicated professionals in the classroom and their students, administrators, parents, and scientists. We acknowledge the thousands of FOSS educators who have embraced the notion that science is an active process and thank them for their significant contributions to the development and implementation of the FOSS program.
