Next Generation Science Standards

This reference directory covers the Next Generation Science Standards (also high school, organized here by Disciplinary Core Ideas) and list the expii topics in each category. Due to the crowdsourced nature of expii’s explanations, they may not fully align with the intention of the standards in practice. If you see an explanation that you believe is misaligned, you may suggest edits or write a separate explanation that is more appropriately aligned for your purposes.
