WHST.9-10.1 Discipline-specific argument writing

Write arguments focused on discipline-specific content.

Why water teaches this standard well

High school science and social studies students argue discipline-specific water questions, such as whether the data support switching a city's water source or whether a proposed regulation's costs justify its benefits. Claims must stand on lab results, datasets, and primary documents rather than on opinion.

Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
