This course is built on two public frameworks. The science comes from the Next Generation Science Standards (NGSS): performance expectations (what you can do with the content, coded like HS-ESS2-1) plus science and engineering practices (SEP codes, like SEP-8 Communicating Information). The full standards live at nextgenscience.org.

The AI literacy comes from the OECD/European Commission AILit Framework (2026): 19 competences across four domains: Engage with AI, Create with AI, Manage AI, and Shape AI (ailiteracyframework.org). AI literacy is taught to all sections as curriculum: the same way OPVL or the water cycle is. Each block page's footer names the standards that block builds; this page is the whole-course view.
