Within each folder are discussions started by kids.
Teachers check in daily to answer questions, and guide the student discussions.
For example, in the Science folder, you'll find an astronomy discussion with sixteen messages. Navigation is very straight forward, as you point and click your way through the discussions. A form for submitting your own questions is at the bottom of each discussion page. Questions will be answered via email by a school librarian in a couple of days. Most likely, the volunteer will point you to Internet resources where you can find your own answer.
