Increasingly, students of biology, natural resources, health sciences and other applied life sciences are taking calculus. Such students appreciate biological applications, especially since most textbooks rely on a standard set of examples common to physics. These same applications, however, can be portrayed sometimes in an interesting biological setting. In this paper we apply Newton's Law of Cooling to formulate a response to the question: How long should I leave the thermometer in my mouth to take my (body) temperature accurately?
