Just discovered Sirs Discoverer.  Wonderful sight checked out green sea turtles and found out lots of info that I didn't know before.  Love the reading level ability so kids can find articles that are a perfect understanding for them.  Checked out the database features and what a wonderful sight for teachers.  I can see a lot of different uses for learning how to research and look up interesting topics.  The elementary work book would be so handy at teaching young kids how to use the program.  The maps were very interesting too, nice to be able to find different time periods.  Wish there was a way to pull up two maps at once to compare the areas side by side.  Great learning website.
