CBL™/CBL 2™Sensor - pH
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.
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.
Students will analyze the graphs and use the results to identify unknown liquids using only their pH values.
