Engage students in authentic science, technology, engineering, and math experiences using STCMS™ units. These hands-on, practice-based units are centered around specific bundles of Next Generation Science Standard Performance Expectations that result in coherent unit storylines that will engage your middle school students in the investigation of exciting phenomena. Whether your students are planning investigations and designing solutions to explore Newtonian physics through objects that roll, fall, and collide, or they are gathering evidence and making predictions about reproduction and heredity, STCMS is the only way to prepare your students to be the next generation of scientifically literate citizens.
