Earth and space. The student knows that there are recognizable patterns in the natural world and among objects in the sky. The student is expected to:
A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
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.9
Earth and space. The student knows that there are recognizable patterns in the natural world and among objects in the sky. The student is expected to:
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.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.9.C
compare and explain how superposition of quantum states is related to the wave-particle duality nature of light; and
