In this lesson, students use Bertie Bott's Every Flavor Beans--a "wild" candy written about in the Harry Potter books and now available in stores--to learn about classification and dichotomous keys. In these activities, students sort jelly beans according to a key and then construct a key for a "new" flavor of beans. Students then build on their knowledge by classifying buttons and constructing their own classification key. (Contains 2 figures, 5 resources and 3 online resources.)
