Product Description
In this inquiry lab, students test a variety of simulated household substances, analyze the data to determine the substances' pH values and then categorize them as an acid, a base or neutral. Students use three types of pH tests (blue litmus paper, pH paper and cabbage juice indicator) to determine the pH values of the seven substances. The conclusion questions include real life scenarios regarding the taste of acids, the pH of blood and the use of antacid tablets.

I've used this lab successfully in both my Chemistry and Biology classes. In the Biology courses, it links well with lessons on homeostasis and the concept of a pH value. The lab can be completed individually or run in groups of two.

The solutions used in the lab are created using pH tablets to preserve the transparency needed for the cabbage juice indicator test. This results in easy-to-read color changes. Plus, all leftover substances can be reused the following year without worrying about spoilage.
