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 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 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.

1st Grade (1) Heredity
1.LS3.1 Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents.
Clarification Statement: Examples of patterns could include features plants or animals share. Examples of observations could include that leaves from the same kind of plant are the same shape but can differ in size, and that particular breed of dog looks like its parents but is not exactly the same.
Assessment Boundary: Assessment does not include inheritance, animals that undergo metamorphosis, or hybrids.
Science and Engineering Practices	Disciplinary Core Ideas	Crosscutting Concepts
Constructing Explanations Make observations (firsthand or from media) to construct an evidence-based account for natural phenomena.	Inheritance of Traits Young animals are very much, but not exactly like, their parents. Plants also are very much, but not exactly, like their parents. Variation of Traits Individuals of the same kind of plant or animal are recognizable as similar but can also vary in many ways.	Patterns Patterns in the natural world can be observed, used to describe phenomena, and used as evidence.
