Performance expectationDevelop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
Examples of models could include drawings, diagrams, and texts, such as drawings of what happens when two charges of opposite polarity are near each other.
Assessment is limited to systems containing two objects.
Atomic structure, interaction of subatomic particles, binding energy, bond formation, polarity, intermolecular forces, non-ideal gas behavior.
This performance expectation appears in more than one course map. The note above is the scope NYSED specifies for Physical Science: Chemistry.
Every item written to HS-PS3-5 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.
Developing and Using Models
What a student at each level can do with HS-PS3-5. These drive how a cluster spreads difficulty across its items.
Summarised by ScienceIQ from the NYSED Performance Level Descriptions for Physical Science: Chemistry. These are our wording, not the Department’s — the official descriptions are the authority.
Use a model or provided information to identify forces or energy changes between interacting objects.
Use a model to describe or show forces between objects or energy changes due to interaction.
Develop a model of interacting objects showing forces or energy changes.
Develop and use a model of electric or magnetic field interactions to illustrate forces and energy changes.
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.
