Modern Marvels Engineering!

You can use this in your classroom.  I recommend posting a link for the video on your class's Edmodo page so that if someone is absent, they can still check out their assignments.  I like showing Modern Marvels Engineering because I believe they provide educational value while showing students something that they are familiar with in their daily lives.Modern Marvels Brooklyn Bridge

Online there is also lesson plans that you can use to go with this program. http://www.history.com/classroom-study-guides
