1 CPO Science Foundations of Physics c2016 and the NGSS It is no coincidence that the performance expectations in the Next Generation Science Standards (NGSS) are all action-based. The NGSS champion the idea that science content cannot be separated from science practices and crosscutting concepts. CPO Science Foundations of Physics c2016 is committed to that same philosophy. The result is a program that starts with active investigations and ends with students possessing in-depth understanding of key science concepts and well-honed science and engineering skills. Mastering science comes from doing science. CPO Science provides educators with the tools they need to help their students not only meet the NGSS performance expectations, but exceed them. With abundant support and foundational content at their fingertips, educators can make whatever instructional decisions are necessary to ensure the success of all students.
