BrianPop: Six Kingdoms"How are all the species in the world categorized? In this BrainPOP movie, Tim and Moby introduce you to the six groups, or kingdoms, that contain every form of life on Earth. You’ll learn about some of the history of classification, beginning with the Greek philosopher Aristotle, who was one of the earliest naturalists. His system of classification lasted more than 2,000 years! Tim will also show you how this science has drastically changed over the last 200 years, moving from a comparison of traits to a study of genetics and evolution. Discover which kingdom you belong to and what characteristics you’d have if you fell into one of the other five kingdoms. Once you know about the six kingdoms of life, you’ll be a classification king… or queen!"
