A Sweet Drink

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.

Key Steps

    In this activity, students will dissolve a sugar cube in a beaker of water. They will do this for three different water temperatures. The CBL 2 will record the temperature of the water before the sugar cube is dropped in and the time it took for the sugar to dissolve.

    Students will record the data they have collected and then graph it as a scatter plot. They will also have the calculator fit a linear function to data. Using the line and the scatter plot students will analyze how water temperature affects the dissolving time.
