Yesterday, we went to the Greensboro Science Center for a field trip for my son's birthday. It has a small zoo and a tiny aquarium, and a few other displays, including a rope course high above the zoo. Not very science oriented, but we had fun. The aquarium had a variety of small stingrays that you could touch, sharks, penguins, octopus, crabs, jellyfish, seahorses, and other colorful fish.
