Abstract
Two polymer–plastics experiments were developed for upper-level chemistry laboratories. In the first experiment, students prepare plasticized biopolymer films from aqueous solution and measure the dependence of mechanical properties on chemical composition. In the second experiment students encapsulate salicylic acid in a polymer matrix of poly(lactic acid-co-glycolic acid) and measure its release into water, which illustrates the use of polymers in drug-release biomedical applications.
Supplement
Instructions for students, notes for the instructor, and the content-based questionnaire are available.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
