Zoologists study animals of all shapes and sizes. Zoologists help us understand how animals live and interact with the world. On this Science Trek, host Joan Cartan-Hansen and her guests will answer students’ questions about zoology. Cartan-Hansen will be joined by Steve Burns, director of Zoo Boise and by Holly Holman, Zoo Boise’s veterinarian. Viewers will also visit Zoo Boise and learn about its very special conservation program.
