To create an excellent WebQuest for your students you also need to consider the Learning Theory on Multiple Intelligences (MI).
I was terribly excited years ago now when Prof. Howard Gardner was going to address us about his Theory on MI. I had implemented his theory into my teaching practice especially when teaching senior Chemistry. It was so successful that ex-students still come up to me in the streets and shopping malls saying ... "Do you remember when you got us to....?" They still remember these lessons because I implemented this theory into practice.
However, at this conference I attended, Prof. Gardner was such a disappointment - he simply READ from his notes (and these were on the big screen anyway!).
All I can say is that MI is great when it is applied!!!
Here are some resources you might find useful:
MI - this site gives the theory behind the eight Intelligences (although there is a belief that more Intelligences exist):
Linguistic intelligence ("word smart")
Logical-mathematical intelligence ("number/reasoning smart")
Spatial intelligence ("picture smart")
Bodily-Kinesthetic intelligence ("body smart")
Musical intelligence ("music smart")
Interpersonal intelligence ("people smart")
Intrapersonal intelligence ("self smart")
Naturalist intelligence ("nature smart")

this test is great fun for yourself and your students! It also gives you as the teacher some food for thought as to how you are presenting material in class!
