Students are using their cellphones to do classical chemistry experiments, a technique that could save high schools thousands of dollars.
University of Minnesota alumnus Eric Kehoe and associate chemistry professor Lee Penn developed the technique to evaluate a liquid’s concentration by simply taking a photo with a smartphone.
Penn has used the technique for the past two years in her freshman honors seminar, and Kehoe, who is a chemistry teacher at Janesville-Waldorf-Pemberton High School, has used it in his classes.
