Bone Lab (grades 2-3) Because this program is fully booked, we are no longer taking reservations for the 2007-2008 School Year. Interactive laboratory sessions make science "come alive." The Bone Lab compares animals and their skeletons. The one-hour programs are conducted in the Zoo's classroom. The cost is $4.00 per student /$5.00 adult chaperone. Credentialed teachers are free. The fee includes admission to the Zoo. Programs are available Tuesday, Wednesday and Thursday mornings, during the months of October through April. Teachers should book early by calling (714) 647-6575; progams are usually full by October.
