We report the development and implementation of coupled class and lab materials to introduce students to the interdisciplinary applications of physical chemistry. These materials, inspired by the Physical Chemistry with a Purpose series, combine a guided reading of a recent paper from the literature with a complementary laboratory experiment using inexpensive and modular laboratory equipment. We report on two modules: an introduction to nanomaterials and a spectroscopic study of complex kinetics. In the nanomaterials study, students synthesize and characterize quantum dots by measuring the emission spectra. In the classroom they do a guided reading of a paper demonstrating the use of quantum dots to detect toxins. In the complex kinetics module, students use absorbance spectroscopy to measure the kinetics of the Belousov-Zhabotinksy [BZ] reaction. They model this reaction first with a predator/prey relationship, and determine the kinetic parameters of the oscillating Belousov-Zhabotinksy [BZ] reaction. In the classroom, they discuss a paper on complex atmospheric kinetics. We will also report the results from pre and post test surveys of student attitudes, and assessments of learning outcomes.
