What is the role of informal science education in supporting the vision for K-12 science education?

There can be a mistaken impression that the new vision for K-12 science education is only relevant to classroom science instruction. But youth frequently engage in powerful science and engineering activities that take place after or outside-of-school. They learn STEM content, engage in STEM practices, and develop an understanding of how STEM is used in the world. To capitalize on those assets, educators and other stakeholders should learn about, leverage, and broker connections for youth across the STEM learning experiences available in and out of school.
