Dichotomous key – classifying organisms with yes/no questions

Integrated ScienceCells & OrganismsAges 11–12

Students pick an organism (from 8 familiar animals or 6 familiar plants) and answer a series of yes/no questions about its features; the dichotomous key diagram on the canvas highlights the path taken until the organism is identified. Guided mode checks each answer and explains it; exploration mode lets students answer freely to see which organism the key leads to.
