Thanks in part to Rudolph the Red-Nosed Reindeer some children don’t believe that reindeer (caribou) are real animals. SciShow Kids seeks to remedy that in their latest video 4 Facts to Know About Reindeer. Through the video kids can learn why reindeer are called caribou in North America. The lesson also teaches students how reindeer have adapted to find food and stay warm in cold weather. The video concludes with an explanation of why reindeer migrate.
