Performance expectationDesign, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
Emphasis is on both qualitative and quantitative evaluations of devices. Examples of devices could include Rube Goldberg devices, wind turbines, solar cells, sound level or light meters, solar ovens, and generators. Examples of constraints could include use of renewable energy forms and efficiency.
Assessment for quantitative evaluations is limited to total output for a given input. Assessment is limited to devices constructed with materials provided to students.
Every item written to HS-PS3-3 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
Constructing Explanations and Designing Solutions
Phenomenon stimulus, connected items across the required types, answer key, rubric and figures drawn deterministically from a structured spec — in the format your students will sit.
