The Full Option Science System springs from a philosophy of learning at the Lawrence Hall of Science that has guided the development of successful active-learning science curricula for more than 25 years. The FOSS developers are dedicated to the proposition that students learn science best by doing science. Teachers and students do science together when they open the FOSS kits, engaging in enduring experiences that lead to deeper understanding of the natural world.
*Alternative Module. FOSS is providing more options to align with more state standards.
