HS-ETS1-1 Specify criteria and constraints for a major global challenge
Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
Why water teaches this standard well
Water scarcity and safe drinking water are among the defining global challenges of the century, giving this standard a compelling real context. Students can specify measurable criteria and constraints for supplying a water-stressed city, the same framing engineers use before designing a desalination or reuse project.
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.
