OpenSciEd is rolling out one of the first curricula that both aligns with the Next Generation Science Standards and, as an open science education resource, is free. The nonprofit is working to produce an entire science curriculum that runs from elementary through high school, is freely downloadable and is designed to be used with low-cost standard laboratory equipment and materials. The organization is led by 10 partner states, science educators, curriculum developers and philanthropic organizations, including BSCS Science Learning, Northwestern University, Boston College, the Charles A. Dana Center at the University of Texas at Austin and Digital Promise.
