Next Generation Science Standards - 
Created by MasteryConnect, this "free" app takes a close look at the new Next Generation Science Standards (NGSS). You can scan standards by topics, domains, conceptual progressions and keywords. MasteryConnect teamed up with the National Science Teachers Association to create this effective and easy-to-use interface. The robust resource area includes an overview of the NGSS, a detailed explanation of how the new standards are structured, and frameworks. The appendices include conceptual shifts from old to new national standards, responses to public drafts, and a section on how implementation of the NGSS prepare students for college and career. Looking for connections to math? Connections to literacy? Model middle and high school course mapping? Those are included too, as well as many more valuable resources to ensure clearer understanding of science.
