It is a matter of fact that field trips are on a decline. The culprits are possibly cost, time, and even technology. With technology providing vast amounts of opportunity, field trips to the zoo can be substituted for a much cheaper (usually free) alternative. (Speaking of which, I just posted last week about Connected Classrooms by Google+.)
The first grade teachers of Rome City, Ms. Ruse and Ms. Doyle had another idea in mind. Instead of utilizing technology to substitute for the field trip, why not use it to be persuasive? The students planned out what they wanted to say, wrote out their text using Pic Collage (now we would use Pic Wall), and used Shadow Puppet to record their persuasive writings.
