All About Explorers is a series of lessons for elementary and junior high students (can be explored by a single or several lessons, or as a webquest) that demonstrates that just because something is out there for the searching does not mean it is worthwhile.
For example, if a student is doing a search for information about Christopher Columbus, typically they will just do a Google search or type something like www.columbus.com. If you click on this link, that is not helpful. Neither is www.columbus.org, which takes you to the Columbus, OH, Chamber of Commerce.
This site carefully takes students through what looks like a typical research project or webquest, and has plenty of opportunities built in for students to make choices and look critically at the information they are finding.
It's easy to use for teachers and students - for teachers wanting to see what is offered, the site is easy to navigate.
