Science for All 
Great article. Roger has distilled and presented the essence of science and engineering practices from the framework in way that makes it accessible. Should be a cornerstone reading as we move ever closer to the Next Generation Science Standards
I agree- I think this is article is very helpful in clarifying some key issues such as Why is engineering here? and Where is my Inquiry?
