The brother-sister duo of Charlie and Kirby Engelman hosts this series that explores the science between the planet and its wildlife. A different topic is explored in each episode by ecologist Charlie and artist Kirby. The siblings look to inspire young people to question the "how" and "why" behind the way the world works and encourage the viewers to go out and try to discover the answers to their own questions about the world. The series is produced in association with National Geographic Kids, and both hosts are National Geographic Junior Explorers.
