This is a great page on the National Science Teacher's Association page that helps to outline all the Science and Engineering Practices (SEP) of the Next Generation Science Standards.
​
This resource can be used for quick access to the explanation of the practice. When you click a specific practice, it takes you to a page that better explains that SEP, and what it looks like at each level of schooling. It helps the teacher to determine the bounds of the SEP from K-2, 3-5, Middle, and High to gauge what they have been asked to do and what the expectations will be.
This is a great page on the National Science Teacher's Association page that helps to outline all the Cross Cutting Concepts (CCC) of the Next Generation Science Standards.
​
This resource can be used for quick access to the explanation of the CCC. When you click a specific CCC, it takes you to a page that better explains that CCC, and what it looks like at each level of schooling. It helps the teacher to determine the bounds of the CCC from K-2, 3-5, Middle, and High to gauge what they have been asked to do and what the expectations will be.
​
There is a great deal of overlap between the CCC and literacy practices.
