The Oklahoma Academic Standards for Science (OAS-S) are three-dimensional performance expectations representing the things students should know, understand, and be able to do to be proficient in science and engineering. Performance expectations are considered standards and include a science and engineering practice (indicated in blue and represent everyday skills of scientists and engineers), disciplinary core ideas (represented in orange and represent science ideas used by scientists and engineers), and a crosscutting concepts (indicated in green and represent ways of thinking like scientists and engineers).

Each dimension in the OAS-S grows in complexity and sophistication across the grades. To learn more about the prior knowledge and skills students have developed (or future knowledge/skills) associated with that specific dimension, each section in the standard below is hyperlinked to that specific vertical learning progression page.

Earth and Space Science (ES) Earth's Systems
ES.ESS2.1 Develop a model to illustrate how Earth’s internal and surface processes operate at different scales of space and time to form continental and ocean-floor features.
Clarification Statement: Emphasis is on how the appearance of land features (such as mountains, valleys, and plateaus) and sea-floor features (such as trenches, ridges, and seamounts) are a result of both constructive forces (such as volcanism, tectonic uplift, and mountain building) and destructive mechanisms (such as weathering, erosion, and landslides or mudslides).
Assessment Boundary: Assessment does not include memorization of formation details of specific geographic features of Earth’s surface.
Science and Engineering Practices	Disciplinary Core Ideas	Crosscutting Concepts
Developing and Using Models Develop a model based on evidence to illustrate the relationships between systems or components of a system.	Earth's Materials and Systems Earth’s systems, being dynamic and interacting, cause feedback effects that can increase or decrease the original changes. Plate Tectonics and Large-Scale System Interactions Plate tectonics is the unifying theory that explains the past and current movements of rocks at Earth’s surface and provides a framework for understanding its geologic history. Plate movements are responsible for most continental and ocean-floor features and for the distribution of most rocks and minerals within the Earth's crust.	Scale, Proportion, and Quantity Some systems can only be studied indirectly as they are too small, too large, too fast, or too slow to observe directly.
