What do science students wonder about?

Greetings!  This question was posed by David Rosen in his discussion with Brooke Istas on a different thread:

"What do your science students wonder about; what questions or concerns do they have about science?"

For the background on that question, please read this comment, "Science Blended Learning", in which Brooke uses student questions to form teaching and learning activities involving online investigations outside of class time.

Great idea, David!
