Learning about webquests

All of these Webquests have pros and cons but the best two are:
A Creative Encounter of the Numerical Kind and Travel Agent to Ancient Egypt.
The worst two are The Diary of John Wilkes Booth and The Environmental Problems with Landfills.
The Diary of John Wilkes Booth has a good introduction to draw your attention.  It was pretty simple steps to follow. It seems like they could have done more with it by using additional multimedia.
The Environmental Problems with Landfills had a good introduction  It  builds on prior knowledge. The evaluation part was missing.
Travel Agent to Ancient Egypt Webquest was very interesting. It was easy to get through and it had a video. It allowed students to become familiar with Powerpoint.
A Creative Encounter of the Numerical Kind used animation to pull kids into it.   It was a long process but it describes each step .
