Use a pH sensor to measure the pH of several different household chemicals
Working with common household chemicals, students develop an understanding of the pH scale. In this activity, students investigate and observe how red cabbage juice changes color in the presence of acids and bases and relate this visual indicator to the numbers of the pH scale.
Additionally, students will be able to:
Recognize that substances often are placed in categories or groups if they react in similar ways, such as an acid or base
Make explanations and predictions from evidence and drawing logical conclusions
Gain skills and confidence in using a scientific measurement tool—the pH sensor—as well as the spreadsheet and graphing capability of a computer to represent and analyze data
Students gain experience conducting the following procedures:
This experiment may require software and an interface for data collection.
