60 Second Lectures

What Makes a Poem a Poem? A 60 second lecture.
Instructors from University of Pennsylvania's School of Arts and Sciences take a minute each spring and fall to offer their perspectives on a wide variety of topics.  You may find these 1 minute talks entertaining and who knows, some might be useful in a lesson design.
The 60 Second Lectures site was discovered on the blog titled, Free Technology for Teachers.
