Enough talk about zoo animals....
Pack up a lunch and take the kids out to see a real zoo!
Point out the different animals they learned about in preschool and ask them questions to test their memory. "What do tigers eat? Are they carnivores or herbivores? Where do penguins usually live? etc."
Often there will be scheduled feedings for different animals throughout the day, which are always interesting to watch.
Take lots of pictures and allow children to take a few pictures too.
On the ride home, have them talk about their favorite animals and some interesting things they observed.
