The Next Generation Science standards require eight scientific and engineering practices. This product includes a poster for each practice with visual representations to help explain (great for ELLs). They are attractive with colored dot backgrounds and owls on the side. The purpose for the bulletin board would be to reinforce the scientific and engineering practices while problem solving/ doing science experiments/ and inquiry projects. You could use it as a CAFE type bulletin board also, in which the students put their name and/or picture next to the practice that they have used while working on science/math/engineering. This gives them ownership of the strategies and helps them stay engaged in the lesson.
