About 1/3 of the test is devoted to NGSS Science and Engineering Practices (SEP), Cross-Cutting Concepts (CCC) and Engineering Design & Applications. Please click on the links below and watch the associated videos for each of the 8 SEPs, the 7 CCCs and Engineering Design.  These are woven into the content of all workshop sessions and provide the lens through which we study the physical sciences, the life sciences, and the earth & space sciences.
