FOSS makes students active investigators of phenomena.

FOSS turns students from passive spectators to active investigators. Students step away from their screens and explore phenomena with their own hands.



FOSS carefully designs a sequence of investigations, or storylines, to support students in figuring out elements of the phenomenon. Students investigate elements of the phenomenon, incorporating opportunities to make sense of their learning, devise and revise models, and reflect on what they still need to learn.


Local and Relevant Phenomena

Every phenomenon used in FOSS is local and relevant to your students. As they make sense of the phenomenon through a coherent sequence of activities, they use notebooks to record observations, discuss, reflect on, and revise their models and explanations.


Student Empowerment

FOSS empowers all students to comprehend and explain what they are observing, so they can deepen their understanding of the phenomena they are exploring.
