Temperature's Effect on the Rate of Dissolving

Published on 09/13/2010

Activity Overview

Students use the CBL 2™ with the temperature sensor to collect data and then analyze that data to determine the effect of temperature increases on the rate of dissolving.

Key Steps

  • Image

    Students compare the amount of time it takes a sugar cube to dissolve in different water temperatures. Using a temperature sensor, students will collect the time and temperature of the sugar cube dissolving in water temperature of 5°C, 25° C, and 35° C.

    After the calculator creates a scatter plot of the data that was collected, students will analyze the data using a linear regression line.
