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 concept (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.

6th Grade (6) Earth's Systems
6.ESS2.1 Develop a model to describe the cycling of Earth’s materials and the flow of energy that drives these processes within and among Earth’s systems.
Clarification Statement: Emphasis is on how energy from the sun and Earth’s hot interior drive processes that cause physical and chemical changes to materials within and between the geosphere, hydrosphere, atmosphere, and biosphere. Examples of processes could include melting, crystallization, weathering, deformation, and sedimentation, which act together to form and change rocks and minerals through the rock cycle.
Assessment Boundary: Assessment does not include the identification or naming of minerals.
Science and Engineering Practices	Disciplinary Core Ideas	Crosscutting Concepts
Developing and Using Models Develop and use a model to describe phenomena.	Earth's Materials and Systems All Earth processes are the result of energy flowing and matter cycling within and among the planet’s systems. This energy is derived from the sun and Earth’s hot interior. The energy that flows and matter that cycles produces chemical and physical changes in Earth’s materials.	Stability and Change Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time and forces at different scales, including the atomic scale.
