HS-PS1-3

SCUSD NGSS Curriculum Guide


 * HS-PS1-3: 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, not on naming specific intermolecular forces (such as dipole-dipole). Examples of particles could include ions, atoms, molecules, and networked materials (such as graphite). Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension.] [//Assessment Boundary: Assessment does not include Raoult’s law calculations of vapor pressure.//]

Science Background for the Teacher:
