"Inspiring STEM Educators: The NASA Physics and Engineering Collection is designed to bring real-world applications of physics and engineering concepts into high school classrooms. The videos and interactive presentations that make up the collection are drawn from NASA's vast collection of media resources."
"Try Engineering is a site that hosts lesson plans and games designed to get students interested in engineering. The lesson plans, 114 in all, are arranged according age and engineering topic. The lesson plans can be downloaded as PDFs.
The games section of Try Engineering features 29 games. Some of the games were developed specifically for Try Engineering while others are hosted on other educational sites like those of NASA and PBS. Like the lesson plans, the games collection cover a variety of topics including solar energy, space science, and bio-engineering."
