• Resumen

  • Engaging students who are not chemistry majors is a signi?cant challenge. Plaster of Paris is a substance well-known to undergraduate students from early life arts-and-crafts endeavors.

    Within, a lab is described that connects the synthesis and use of plaster of Paris with a number of chemical principles including stoichiometry, acid-base titration, hydration, and reaction yield.
