LinkEngineering is a collaboration between the National Academy of Engineering and five partner organizations. Funded by Chevron, the LinkEngineering website is designed to support teachers, teacher educators, and administrators at all levels of PreK-12 education to more effectively implement engineering in classroom and out-of-/after-school settings. LinkEngineering is not principally a collection of stuff. Rather, it is a community of practitioners learning from one another.
You can browse the site without creating an account, but you will not be able to contribute to or get feedback from the LinkEngineering community without registering. Registration is free.
