Classification and Keys 15 October 2021 LO: Use and create branching keys to identify organisms • Classifying means putting things into groups based on their characteristics. • The organisms in the picture would be put into the animal kingdom. • They all have backbones, so would be grouped together as vertebrates. • In addition, they would be classed as mammals because they all breath using lungs, live on land give birth to live young. • A branching key is a type of ‘flow chart’ with yes or no questions used categorise objects. • One question you could ask to help identify the different breeds might be do they have a long tail Key terms: Classification, Key, Vertebrate
