What should I emphasize in my upcoming interview with the American Museum of Natural History?

Three components really make up this internship: a commitment to education or academia in general, a commitment to public speaking, and a commitment to any of the topics that make up the halls of the museum (namely, in broad terms, physical anthropology, zoology, and environmental science). Any strongly expressed interests in these three subjects will help interviewees for the hiring process (experience working with children will help as well).
