Download a PDF of all standards grouped by Disciplinary Core Ideas (DCI) or click on a grade band below for individual DCI bundles of standards. DCIs are the fundamental ideas that are necessary for understanding a given science discipline. The core ideas all have broad importance within or across science or engineering disciplines, provide a key tool for understanding or investigating complex ideas and solving problems, relate to societal or personal concerns, and can be taught over multiple grade levels at progressive levels of depth and complexity. 

You may also view topic arrangements of standards or search for individual performance expectations. To the right under Related Resources are Storylines together with PDFs of related standards. 

Storylines are statements that describe the context and rationale for the Performance Expectations (PEs) in each grade band and section.
