I just learned about Zunal from Isabel Neves in Portugal.  Zunal is an easy way for teachers (and students) to create webquests.    I know there are some specific parameters involved in using the term “webquest,”  so  you can also use Zunal to create much simpler “online scavenger hunts.” 

At their most basic, it can be a series of questions students have to answer, along with links to websites where the information can be found.

Zunal also acts as the host for the webquest or scavenger hunt after its been created.

I’ve placed the link on my Teacher’s Page under Webquests.
