FOSS science investigations take a collaborative, cooperative approach. Students work in assigned roles according to the FOSS program. This resource helps students to understand their jobs and follow a schedule. Assign each student in the group a color, then follow the four week cycle according to this poster. I put a colored dot on science notebooks to signify their color. Print these signs small and glue them into science notebooks, project them on interactive board, or print them and display them on a bulletin board.
