Expectations

SG1.a
Construct an explanation based on evidence for the formation of the Earth. (Clarification statement: The mechanisms of accretion and differentiation should be addressed here. Include an understanding of Earth’s elemental composition, the Nebular Theory and the Iron Catastrophe Theory.)
SG1.b
Develop a model of the Earth’s internal structures including both physical (i.e., lithosphere, asthenosphere, mesosphere, outer core and inner core) and chemical (crust, mantle, core) layers. (Clarification statement: Include how data, computer technology, and computational thinking are used to determine thicknesses and chemical composition of the layers.)
SG1.c
Construct an explanation based on evidence for the origin and evolution of Earth’s hydrosphere and atmosphere. (Clarification statement: Include the ideas of outgassing, photochemical dissociation,

photosynthesis and comet delivery.)
