In the Laboratory
The Water Project: A Multi-Week Laboratory Project for Undergraduate Analytical Chemistry

Abstract
A five-week water project has been incorporated into a quantitative analysis course to increase student interest, independence, and critical thinking skills. Each of nine students in the class analyzed water samples for a particular chemical species using two different methods. Students chose to use spectrophotometric, atomic absorption, titration, or ion-selective electrode methods for their analyses. Results were reported in writing and through a presentation to a public forum. Based on student-survey results, the water project was overwhelmingly popular with students while challenging them to think critically and work independently. Students agreed that the seven prior laboratory assignments in the course helped prepare them for the water project.
