Core Idea - Motion and Stability: Forces and Interactions
[HS.CHEM.2.6] - Communicate scientific and technical information about the molecular-level structures of polymers, ionic compounds, acids and bases, and metals to justify why these are useful in the functioning of designed materials.* Clarification Statement: Examples could include comparing molecules with simple molecular geometries; analyzing how pharmaceuticals are designed to interact with specific receptors; and considering why electrically conductive materials are often made of metal, household cleaning products often contain ionic compounds to make materials soluble in water, or materials that need to be flexible but durable are made up of polymers. State Assessment Boundary: State assessment will be limited to comparing substances of the same type with one compositional or structural feature different.
[RCA-ST.9-10.1] -
Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions.
[SLCA.9-10.4] -
Present information, findings, and supporting evidence clearly, concisely, and logically such that listeners can follow the line of reasoning and the organization, development, vocabulary, substance, and style are appropriate to purpose, audience, and task.
[RCA-ST.11-12.1] -
Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account.
[AI.N-Q.A.1] -
Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.*
[AI.N-Q.A.2] -
Define appropriate quantities for the purpose of descriptive modeling.*
[AI.N-Q.A.3] -
Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.*
[HS.CHEM.1.3] -
Cite evidence to relate physical properties of substances at the bulk scale to spatial arrangements, movement, and strength of electrostatic forces among ions, small molecules, or regions of large molecules in the substances. Make arguments to account for how compositional and structural differences in molecules result in different types of intermolecular or intramolecular interactions. Clarification Statements: Substances include both pure substances in solid, liquid, gas, and networked forms (such as graphite). Examples of bulk properties of substances to compare include melting point and boiling point, density, and vapor pressure. Types of intermolecular interactions include dipole-dipole (including hydrogen bonding), ion-dipole, and dispersion forces. State Assessment Boundary: Calculations of vapor pressure by Raoult’s law, properties of heterogeneous mixtures, and names and bonding angles in molecular geometries are not expected in state assessment.
