### Abstract

At the end of a chapter on Newton's Law of Cooling, Nagle and Saff's
Fundamentals of Differential Equations and Boundary Value Problems
poses the following problem:

We will demonstrate a classroom experiment of this problem,
explain how to import the data into Maple, and look at
an interactive Maple demo created to complement the experiment.
We will then discuss problems that arise
with the experiment and with the model of Newton's law of cooling.
We will summarize research done by a physicist analyzing cooling data
and will discuss a better cooling model to use.

To conduct the experiment,
we used a CBL unit, hand held technology that comes with
temperature and other probes, which is becoming popular in
high school and college classrooms. The interactive Maple demo, where
students must answer questions in order to progress,
can be found as
