The TeachEngineering website is a resource for teachers who seek to make engineering concepts come to life for students in grades K-12. It is also worth nothing that some of the resources are appropriate for college-level students. Funded with money from the National Science Foundation, a team of university researchers worked to create a searchable web-based digital library of free and accessible curriculum resources. The rationale behind teaching engineering to K-12 students is helpfully explained to visitors in the "K-12 Engineering" tab near the top of the page. To search or browse the database, visitors can use such criteria as "Lessons," "Subject Areas," or "Educational Standards." Other ways visitors can view the curriculum include the highlighted "Editor's Picks," "Most Popular," and "Recently Added" sections. The student activity "Amusement Park Ride: Ups and Downs of Design" is the May 2011 Editor's Pick.
