Colorado Science Standards

The Colorado Academic Standards in science represent what all Colorado students should know and be able to do in science as a result of their preschool through twelfth-grade science education. Specific expectations are given for students who complete each grade from preschool through eighth grade and for high school. These standards outline the essential level of science content knowledge and the application of the skills needed by all Colorado citizens to participate productively in our increasingly global, information-driven society. 

Colorado's District Sample Curriculum Project: This fall, over 500 Colorado educators, representing 61 school districts, participated in curriculum design workshops that resulted in the creation of 670 curriculum samples based on the Colorado Academic Standards (CAS). Utilizing a Colorado-designed and refined template, the samples provide organizing structures for addressing the grade-level expectations (GLEs), evidence outcomes (EOs) and 21st Century Skills that build students' mastery of the standards at each grade level. As voluntary resources for districts, the samples:

  • Represent the translation of the CAS into unit overviews for all (10) content areas, grades k-12
  • Illuminate possibilities for sequencing grade-level and content-specific standards across courses/years
  • Offer one possible foundation for exploring standards-based unit and lesson-plan development

The samples, the blank template upon which they are based, and a template with definitions can currently be accessed on this website.

Teaching the Colorado Academic Standards in science is supported through a wide array of free instructional resources. This webpage lists just a few of these resources and will be updated regularly. If you are an educator in Colorado and have suggestions for a great free resource please contact Joanna Bruno, Science Content Specialist, at 303-919-3907 or For additional opportunities consider Professional Development.
