Engineering Class using Audio boo

We have been following audio clips about Engineering and how it relates to today's students.  My students are learning that there are alot of jobs in the engineering field that are avalible.  I'm having students set up there own audio boo accounts and/or post comments about the boo's that we discuss in class.  The students have responded ok.
