Presentation Transcript

  1. Transition to an Investigative Laboratory Program in Chemistry at Birmingham-Southern College David J. A. Schedler and Laura K. Stultz

  2. Introduction • National Science Foundation Grant • Investigative Laboratories • Development of Laboratory Projects • Examples

  3. Project Goals Curricular Goals • Improved laboratory experience • Better synergy between lecture and laboratory • Connections between chemistry courses Student Goals Improve - Problem solving and collaborative skills - Ability to apply experimental techniques to solve a chemical problem. - Ability to communicate results (written and oral)

  4. Investigative Laboratories • Students discover results instead of verifying them • Experimental protocols are largely student designed • Work is done in collaborative groups • Interpretation of results through data analysis • Group discussion

  5. Project Plan Gradualism Model – stepwise presentation of new material with specific goals Instrumental techniques as common thread - Molecular Modeling - FTNMR (1H and 13C) Project based Laboratories – Reinforces concepts and skills Student involvement in laboratory design

  6. First Semester Focuses on Techniques and Instrumentation • Distillation • Crystallization • Melting point • TLC • GC • NMR

  7. Second Semester Focuses on Application • NMR • FT-IR • Molecular modeling • Stereochemistry and Coupling Constants

  8. Projects should have clearly stated: • Objective • Outcome • Introduction • Theory for the instrumentation to be used • background into the chemistry involved • Experimental Procedure

  9. 2.39 kcal/mol 1.34 kcal/mol

  10. ΨTriplet of Ψtriplets ΨQuintet

  11. Diels-Alder Reaction • prediction of reaction product • carry out reaction using previously learned lab techniques Adapted from: McDaniel, Keith F.; Weekley, R. Matthew “The Diels-Alder Reaction of 2,4-Hexadien-1-ol with Maleic Anhydride: A Novel Preparation for the Undergraduate Organic Chemistry Laboratory Course” J. Chem. Educ.1997, 74, 1465.

  12. Structure Determination NMR IR Mechanistic explanation
