STEM OERCREATE for STEM at Michigan State University provides research-based science curricula developed with funding from the National Science Foundation and other sources. These high-quality project-based learning materials are tightly aligned to the Next Generation Science Standards (NGSS), piloted by dozens of teachers in real-world settings, and then tested for efficacy on large and diverse populations of students. CREATE and MSU provide these materials as Open Education Resources, free to use and adapt by teachers and schools.
