I organized a field trip for our homeschool group to visit the local aquarium. I didn't think it would be that big of an endeavor but it sort of was! We went a couple of years ago and I really wanted to go again- and no one else wanted to organize it- so I volunteered! The aquarium gave us a great rate for an all-day pass that gave us unlimited access to the rides and aquarium so it was hard to pass up this opportunity. We had over 50 kids and their parents attend!
Before we started exploring, the kids had a little class prepared for them by some of the aquarium workers. Their class was jungle-themed. Basically they got to get close to a parrot!
Finally we went outside for the train, carousel, and this thing that took them up in the air and dropped them gradually, bit by bit, back down again. It wasn't one huge drop which is what I initially was worried about! Since we had unlimited passes they went on it a couple of times. Jack even went!
