Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

Clarification statement: Emphasis is on understanding the strengths of forces between particles in solids, liquids, and gases, not on naming specific intermolecular forces (such as dipole-dipole). Examples of particles could include ions, atoms, molecules, and network solids. Examples of bulk scale properties of substances could include the melting point and boiling point, vapor pressure, and surface tension.]

Performance Level Descriptions

PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.

Level 5Level 4Level 3Level 2Level 1

Plan and conduct multiple investigations to gather and evaluate evidence that compares the structure of substances at the bulk scale to explain the strength of electrical forces between particles.

Plan and conduct an investigation to gather and evaluate evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

Given a plan, conduct an explanation or given the results of an investigation or provided information, describe patterns of the relative strength of electrical forces between particles, based on structures, and/or the resulting properties at bulk scale.

Given a plan, conduct an explanation or given the results of an investigation or provided information, make a claim that compares the relative strength of electrical forces between particles of substances at the bulk scale.

Use data from an investigation or provided information to identify a pattern in bulk scale properties of substances as it relates to the relative strength of electrical forces between particles.

NGSS Dimensions

Performance expectation HS-PS1-3 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

• Planning and carrying out investigations: Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.

Disciplinary Core Ideas

• Structure and properties of matter: The structure and interactions of matter at the bulk scale are determined by electrical forces within and between atoms.
• Types of interactions: Attraction and repulsion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects.

Crosscutting Concepts

• Patterns: Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.
