A song written to help students memorize the characteristics that differentiate mammals, reptiles, birds, fish, and amphibians. It is to the tune of "Locked Away" by R. City and Adam Levine. The kids loved singing it and learn the traits of the different vertebrates and are exposed to the terms "class" and "phylum" as well. To see my class sing the song, check out: https://www.youtube.com/watch?v=lRV7cDaRmwg
