I think it is time to put the E back in STEM. (We probably need to focus on the T also- that will have to wait for a future post). Engineering, Go for It provides a focused and engaging set of resources to get students excited about engineering. You can watch video clips (see below) of university students describing their engineering programs or learn about a specific field of engineering.
The site also has a For Teachers section with K-12: lesson plans, class activities, outreach programs, web resources, and more. The lesson plans seem very well developed and contain downloadable documents, video supports, assessments, etc.
Applications for Science Teachers: Any district, school, or teacher looking to add some engineering focus to science instruction would be well served in checking out this site as a starting place.
