Students will move and rotate through various stations set up in the lab or classroom. Each station will have a picture of an animal in the animal kingdom. The students will have a few minutes to look at the picture, observe the characteristics of the animal and determine its classification within the animal kingdom.

Students will choose between three simple classification keys: Dichotomous Key to the Classes of the subphylum Vertebrata, Dichotomous Key to the Phyla of Invertebrates, or Dichotomous Key to Selected Classes of the Phylum Arthropoda. Students will use the appropriate classification key and record their answers in a data table.

It will include Title, Purpose, Procedure, 3 Dichotomous Keys, Data Tables, Follow Up Question, and Teaching Tips.
