The exhibit, organized by the Purdue Agriculture Exhibit Design Center, teaches children that mammals are carnivores, herbivores or omnivores and that there are different types of teeth and feeding habits for each. Among its features are animal skulls, including a tiny weasel and a polar bear. The four-sided display is designed to appeal to children of kindergarten age through fourth grade and their families. It contains components, such as a touch-screen game, for the "tooth sleuths" to test what they have learned about mammals from the exhibit. They also can look at their own teeth in the Tooth Sleuth mirror and to determine their eating category.
