IPC.3.A — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

Previous grade

S.K.8.A

communicate the idea that objects can only be seen when a light source is present and compare the effects of different amounts of light on the appearance of objects; and

S.K.8.B

demonstrate and explain that light travels through some objects and is blocked by other objects, creating shadows.

S.3.8.A

identify everyday examples of energy, including light, sound, thermal, and mechanical; and

S.5.8.C

demonstrate and explain how light travels in a straight line and can be reflected, refracted, or absorbed.

IPC.3.A

hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence. Hypotheses of durable explanatory power that have been tested over a wide variety of conditions are incorporated into theories; and

IPC.7.D

explain how electrons can transition from a high energy level to a low energy state, emitting photons at different frequencies for different energy transitions;

PHYS.9.A

describe the photoelectric effect and emission spectra produced by various atoms and how both are explained by the photon model for light;

PHYS.8.F

investigate the emission spectra produced by various atoms and explain the relationship to the electromagnetic spectrum; and

PHYS.8.G

describe and predict image formation as a consequence of reflection from a plane mirror and refraction through a thin convex lens.
