A Sweet Drink - Adventure 7
 


Activity Overview

Students determine how the temperature of water affects the dissolving time of a sugar cube. They create, interpret and analyze graphs of data, find an equation of the line of best fit, and relate slope to rate of change.

Before the Activity

  • Connect CBL 2™ to the calculator.
  • Plug the TI temperature sensor into Channel 1 (CH 1) on the CBL 2
  • Launch the DataMate program
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 47 - 48 from the attached PDF file for your class
  • Transfer files to student calculators using TI-Navigator™  "send to class" feature


    		• During the Activity

    		Distribute the pages to your class.

    Follow the Adventure procedures:
    Collect Data:
  • Place the temperature sensor in the water at 25 oC
  • Add one sugar cube to the water and start timing
  • Stir constantly and record when the sugar cube is dissolved completely
  • Repeat the experiment with water 5oC and 35oC
  • Plot dissolving time versus temperature of water data
  • Graph the line of best fit
  • Determine the slope of the line
  • Negative slope indicates that as temperature increases, the dissolving time of the sugar cube decreases

    		After the Activity

    		Students analyze the results and answer the questions in the worksheet

    Review student results:
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
