Webquest feedback and podcast thoughts

Well, I received feedback on my webquest, and I am somewhat happy with the grade.  However, I would like to go back in and tweak it a little and see if I can make it better.  I need to add a better hook for the students.  Let the brainstorming commence!

On another note, I am drawing a blank when it comes to this podcast.  I guess I am stuck on the whole "lecture" mindset.  Maybe I could take a current event in my field (science) and discuss the impact that it has on us today.
