Published on 09/05/2010

Activity Overview

In this activity, students will use the CBL 2 with a pH sensor to test the pH of common beverages. They will then choose a graph that will compare the drinks by their pH and use the results to identify mystery solutions.

Key Steps

  • Image

    Students record the pH of several different samples of beverages or liquids.

    Once the data is collected, students will set up and display three different graphs, a bar graph, a scatter plot, and a circle graph, comparing the different beverages and their pH values.

  • Image

    Students will analyze the graphs and use the results to identify unknown liquids using only their pH values.
