Did you ever think you'd see the day when Pokemon would make an appearance in the classroom, and actually be allowed to stay? The activity described here teaches classification, phylogeny, and dichotomy using a set of pseudozoids (false animals), the Unown or Alphabet Pokemon. When students use familiar objects in creating dichotomous keys, they are able to learn from their prior knowledge. Extend an invitation to Pokemon into your classroom today, and teach these tough biological concepts effectively.
