How Cool It Is!

Published on 08/28/2010

Activity Overview

In this activity, students will use a temperature probe to generate a cooling curve and develop an appropriate regression equation to model collected data.

Key Steps

  • Image

    In this activity, students engage in an exploration of the cooling of water. Data is imported into a spreadsheet directly via the use of a temperature probe. They will use a variety of TI-Nspire features to obtain a best fit equation for the generated data.

  • Image

    Visual inspection combined with exponential regression and algebraic manipulation of data results in modeling equations. Students evaluate their results both visually and by inspection of correlation coefficient values.

  • Image

    Students further explore the exponential equation via the use of sliders to visually obtain an appropriate model. ¶ For the second problem, students can use either the given data or the temperature probe to explore heating water.
