Received this from a homeschool loop I'm on and highly recommend it.

The Tennessee Aquarium is having their homeschool day January 23rd from 10AM to 4PM. The cost is $5 per student for Aquarium (both old and new!), and $12.50 per adult. Combo tickets are $8.25 and $16.25 for the Aquarium and IMAX. Behind the scenes tour costs $5. Homeschool students and parents receive 10% discount in the gift shop. This is not up on their web site, yet; I received a letter in the mail. For more information you can contact Bray McDonald at brm [at] tnaqua [dot] org.
