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) Earth's Place in the Universe
|
1.ESS1.2 Make observations at different times of the year to relate the amount of daylight and relative temperature to the time of year.
|
|
Clarification Statement: Emphasis is on relative comparisons of the amount of daylight and temperature in the winter to the amount in the spring, fall, or summer.
|
|
Assessment Boundary: Assessment is limited to relative amounts of daylight, not quantifying the hours or time of daylight.
