7th Grade Standards for Processes that Change the Earth
SC-7-EU-U-4
Students will understand that models of the interior of the Earth have been constructed primarily from inferences based on limited data obtained during earthquakes and volcanic
eruptions. These models are useful, but are open to revision or rejection as new information is obtained
SC-7-EU-S-4
Students will analyze the evidence used to infer the composition of the Earth’s interior and evaluate the models based upon that evidence
SC-07-2.3.1
Students will make inferences and predictions related to changes in the Earth’s surface or atmosphere based on data/evidence.
The Earth’s processes we see today, including erosion, movement of lithospheric plates and changes in atmospheric composition, are predictable and similar to those that
occurred in the past. Analysis of evidence from Earth’s history substantiates the conclusion that the planet has also been influenced by occasional catastrophes such as
the impact of an asteroid or comet. DOK 3
SC-7-EU-U-5
Students will understand that the Earth’s layers vary widely in their properties, and interactions between them can manifest themselves in ways that impact both the Earth and its
organisms.
SC-7-EU-S-5
Students will model the layers of the Earth, explain interactions between them and describe potential results of those interactions
SC-07-2.3.2
Students will explain the layers of the Earth and their interactions.
The use of models/diagrams/graphs helps illustrate that the Earth is layered. The lithosphere is the thin crust and the upper part of the mantle. Lithospheric plates move
slowly in response to movements in the mantle. There is a dense core at the center of the Earth. DOK 2
SC-7-EU-U-6
Students will understand that while some changes to the Earth occur without warning, many changes to the surface or atmosphere can be predicted from available data/evidence.
SC-7-EU-S-6
Students will investigate the forces and processes that change Earth’s surface or atmosphere and analyze data to generate predictions of their effects
SC-07-2.3.1
Students will make inferences and predictions related to changes in the Earth’s surface or atmosphere based on data/evidence.
The Earth’s processes we see today, including erosion, movement of lithospheric plates and changes in atmospheric composition, are predictable and similar to those that
