Students put on their "researcher hats" and walked around recording real world observations of the animals they had been researching. They took notice of the habitat that the zoo had created for their animal of choice, what the animal was being fed, and how the animal was behaving. The zoo did a wonderful job of posting fascinating facts around as well for students to read.
