Johnson City campers were out enjoying the beautiful weather on Tuesday for one of the Department of Parks and Recreation's Nature Camps.
Elementary and middle schoolers spent the day learning about geology and animals like bats, who live in caves.
They even practiced their own echolocation with a hands-on activity.
Naturalist Program Coordinator Connie Deegan told us the campers learned more than just a science lesson.
"I think kids spending time outside is extremely important because they foster, at an early age, curiosity and at some level respect," she said.
Deegan told us this is the second of five weeks of Nature Camps.
In the upcoming weeks, campers can learn outdoor survival skills, animal tracking and identification.
