Classifying Organisms How do scientists classify all of the organisms on Earth? Why Classify Living Things? The study of classifying organisms into different categories is called taxonomy. THINK! – What are some examples of how people use classification systems in their daily lives? Supermarkets Libraries Computer Files THINK! – Why would scientists want to use a classification system for living organisms? To make it easier for them to study and organize living things Levels of Classification Scientists use 7 levels of classification The top level is the broadest (widest) while the bottom level is the most specific (narrow). Levels of Classification mnemonic Kingdom King Philip Phylum Came Class Over Order From Family Germany Genus Sick Species Example of Classification THINK! – What do you notice about the number of organisms in each category as you move down the classification table? The number of organisms becomes smaller and so the category becomes more specific. Naming Organisms Carl Linnaeus came up with a way to name organisms based on observable characteristics. 2/name naming/system His naming system was called binomial nomenclature meaning “two names naming system.” The first name is the organism’s genus. It is always capitalized and italicized The second name is the organism’s species. It is always lowercase and italicized Levels of Classification mnemonic Kingdom King Philip Phylum Came Class Over Order From Family Germany Genus Binomial nomenclature Sick Species Scientific Name Game Can you match the animal with its scientific name? Felis domesticus Canis lupus Ursus horribilis Loxodonta africana Canis familaris Panthera leo Six Kingdoms Today’s classification system has 6 Kingdoms. Watch this BRAIN POP clip titled: “Six Kingdoms.” As you watch, fill in the 6 kingdom names in the blank spaces on your guided notes. THINK! – Can you name the 6 kingdoms?
