Abstract

Resource Image We offer up the claim of a store catalog that its ice ball mold allows users to ``. . . make ice balls that outlast cubes and won't water drinks down.'' We ask students to build a mathematical model to defend or contradict this claim.

Description

In a Brookstone catalog, received by the author on 21 November 2013, there is pictured a ``Rock Glass with Ice Ball Maker,'' a device for making spherical ice balls to put in drinks. The claim is that this device, ``Lets you make ice balls that outlast cubes and won't water drinks down.''

  1. Use mathematical modeling to defend or contradict this claim.
  2. Design an experiment to test this claim.
  3.  Carry out the experiment and use any data in (2) to validate your model in (1).
