Science & Engineering Practices
Each of the eight SEPS in the NGSS has sub-themes that are developed across the grade-bands. For the most part, these are addressed implicitly in Next Gen PET activities/lessons by simply having students engage in them. (A few selected SEPs are addressed explicitly in Units M and SE, and they are indicated in the Target Ideas for those particular units.) The table below shows the SEP sub-themes that students are expected to engage in to a significant degree in both the studio- and lecture-style formats of the material (X) or only in the studio-style format (S). (A unit key is available below the table.)
