The Lawrence Hall of Science at UC Berkeley has long been known for its science education development groups, FOSS, SEPUP, and recently the Learning Design Group (published as Amplify). One of these groups, SEPUP, worked in collaboration with the American Museum of Natural History, WestEd, and the University of Connecticut to develop a model unit for the NGSS at the middle school level. This unit, Disruptions in Ecosystems, earned the second highest rating from Achieve, and is now in re-review for the change made after the initial report.
