from Educators' eZine
More than 30 Federal agencies formed a working group in 1997 to make hundreds of federally supported teaching and learning resources easier to find. The result of that work is the FREE Web site.
FREE stands for Federal Resources for Educational Excellence. The Web sites listed below are excerpted with permission from FREE.
This month, we highlight sites for biology, health and medicine; in other months, we feature other subject areas. You can search our site for the word FREE to find them.
