The first U.S. zoo opened in Philadelphia in 1874.
On the morning of July 1, 1874, the first zoo in the United States, the Philadelphia Zoo, opened its doors to visitors who, for a quarter or less, could visit and view the 813 animals that lived there. Today, the Philadelphia Zoo has more than twice as many animals and four times as many visitors as it had during its first year of operation.
Much more has changed in the zoo than the number of animals and visitors. Visit the Philadelphia Zoo's History Overview to learn more about the first zoo in the United States. Then have your class compare features and aspects of the first zoo with a modern zoo, using the interactive Venn Diagram tool. Ask your students to think in particular about the differences in how animals are cared for and the habitats where they live.
Once your students have considered how zoos have changed over the past century, invite them to imagine the zoo of the future. How will animals be cared for? What will the zoo look like? Who will visit the zoo? What will be the primary mission of the zoo? In small groups, students can explore these questions and then design their own zoo of the future using drawings, posters, dioramas, or a similar display technique.
