Use a familiar song and adorable baby animal pictures to teach youngsters about genetic variation. Begin by listening to "Twelve Variations on 'Ah vous dirai-je Maman,'" which you will need to find online (there are several versions available). Have kids listen for similarities and differences. Next, show the class the pictures of adult animals and their offspring. Using rhythms, the learners will then identify similarities and differences between the adult and baby animals. Use the included rubric to assess understanding.
