We went to the aquarium for a special family outing today. The last time we went was two years ago. Sarah tagged along, but this time she actually got to see the fish (since the last time she was a month shy of her due date ;-)
I tried to make our experience sort of like a field trip, so I made each of the girls an "Aquarium Scavenger Hunt" book. I picked 10 animals I knew the girls would see, jotted a few basic facts about them, and then had a check box for them to mark when we saw each one.
The girls had a blast. It was so fun to see them point and get excited with each new fish they saw. It was also cool because we happened to be there during feeding time for the giant main tank. The girls got to see a diver swim with the fish to feed them. They also got to see the giant sea turtle eat at the tank's surface.
