2020 PH-PS1-8

Page history last edited by Heather Johnston 4 years, 8 months ago

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.

Physics (PH) Matter and Its Interactions
PH.PS1.8 Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
Clarification Statement: Emphasis is on qualitative models, such as pictures or diagrams, and on the scale of energy released in nuclear processes relative to other kinds of transformations. Examples of nuclear processes could include, the formation of elements through fusion in stars, generation of electricity in a nuclear power plant, or the use of radioisotopes in nuclear medicine.
Assessment Boundary: Assessment does not include quantitative calculation of energy released (i.e., binding energy). Assessment is limited to alpha, beta, and gamma radioactive decay.
Science and Engineering Practices	Disciplinary Core Ideas	Crosscutting Concepts
Developing and Using Models Develop, revise, and/or use a model based on evidence to illustrate and/or predict the relationships between systems or between components of a system.	Nuclear Processes Nuclear processes, including fusion, fission, and radioactive decay of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process.	Energy and Matter In nuclear processes, atoms are not conserved, but the total number of protons plus neutrons are conserved.
