Teacher reference · Revised October 9, 2026
Plan the lesson around the work students need to show.
Use the teacher pack for a worked science lesson, answer guidance, a formative rubric and reusable AI prompts. Give students the separate practice sheet.
Historical audit files
The August 27, 2026 audit ZIPs remain available for archival reference. Their lesson scope and checker claims have been superseded by the current guide. In particular, MS-PS1-2 property comparisons need the official assessment scope, and atomic rearrangement is part of the evidence statement. A saved checker result does not establish curriculum alignment, chemical safety or classroom approval.
Use the current materials for the examples discussed in the revised guide. The historical packages are not recommended as current teaching plans.
