The following identifies what disciplinary core ideas (DCIs) are introduced at each grade level/content area for grades K-12

  • Concepts are divided into three domains:  Physical Sciences (PS), Life Science (LS), and Earth & Space Sciences (ESS).  Click on each domain to see K-12 vertical alignment.  The grade level/content areas that include each domain in their curriculum is noted.
  • Each domain is further subdivided into topics (ex:  From Molecules to Organisms).  Click on each topic to see the specific DCIs addressed at each grade level.
