The Logic of Classification: Slide Deck

Section role: Supports the 'Decoding Diversity: Introduction to Keys' section while the teacher formalizes student observations into dichotomous keys and taxonomical hierarchy. Slides: (1) Title — 'The Logic of Classification'; (2) What is Taxonomy? — bullets: definition of taxonomy, purpose of organizing life, connection back to outdoor data collection in the school compound; (3) The Power of Traits — bullets: defining a trait, moving from subjective descriptions like 'pretty' to objective traits like 'has wings'; (4) The Dichotomous Key — bullets: meaning of dichotomous, step-by-step logic of two-choice questions; (5) Building Step One — bullets: example using wings versus no wings; (6) The Five Kingdoms of Life — bullets: broad context showing where small differences fit into the wider biological world; (7) Summary and Next Steps — bullets: preparing to engineer individual keys in the upcoming group task. Closing slide: 'How can two choices help us identify millions of species?' — sets up the group engineering activity that follows.
