Grades K-5

Uncover the secret science behind the care we provide to Denver Zoo’s 3,000 animal residents! Spark your students’ interest in science as you explore real-world animal care challenges in this special discovery day at Denver Zoo. Following a special Secret Science Day map, students will get an insider’s view of the Zoo-learning some of the unique ways our keepers, veterinarians, nutritionists, trainers and exhibit designers meet the challenges of caring for our wild family.

Zoo staff and volunteers will help your students uncover the inside workings of Denver Zoo, encourage them to make observations at exhibits, discuss ideas with their peers and share what they’ve learned. The more they engage, the more they discover-including tips on where to see exciting demonstrations, interact with keepers and vets and meet live animals up close!
