How many of your students know that even today new species are being found all over the globe? Introduce them to the amazing diversity our planet houses with a creative activity about animal variation and classification. They'll use a dichotomous key to classify nine newly discovered species, and then they'll construct their own dichotomous key based on a series of animal pictures, showcasing key animal features. Tip: Have each child create a new species of their own, and then have the whole class use the dichotomous key to classify them.
