Performance expectationPlan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
Emphasis is on analyzing data from student investigations and using mathematical thinking to describe the energy changes both quantitatively and conceptually. Examples of investigations could include mixing liquids at different initial temperatures or adding objects at different temperatures to water.
Assessment is limited to investigations based on materials and tools provided to students.
Every item written to HS-PS3-4 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.
Planning and Carrying Out Investigations
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.
