Title: Molecular Visualization in Chemistry Workshop


1
Molecular Visualization in Chemistry Workshop
  • Scott A. Sinex
  • Prince Georges Community College
  • 22-25 June 2004

Sponsored by the Maryland Virtual High School
2
What we want to accomplish
  • The objectives of this workshop are three fold
  • ? Introduction to a student-based project of
    using a template for producing a webpage
    (http//academic.pgcc.edu/psc/eMol)
  • ? Introduction to the use of FrontPage, Chime,
    and ChemSketch to design web-based activities,
    and
  • ? Develop a collection of web-based activity for
    classroom use.

Enhance student learning in
WHY?
  • General Chemistry
  • Organic Chemistry
  • Molecular Biology

Dynamic and Interactive Technology too!
4
The tools we have
  • ChemSketch chemical structure drawing program
    plus other drawing capabilities
  • Chime/RasMol molecular structure rendering
    software
  • FrontPage build webpages with Chime images
    incorporated
  • plus some other tricks!

5
A journey into molecular geometry
Styrofoam balls and toothpicks
Construct and discover
Ball stick models
Ideal geometries
Chime molecules
Ideal geometries
Lone pair distortion
Molecular polarity
6
The uses in the classroom
  • Multiple representations
  • 2D to 3D in various modes
  • Cartoons for proteins, nucleotides
  • Interactive viewing of
  • molecules

7
and more uses
  • Measurements on molecules
  • Bond lengths
  • Bond angles
  • Torsion angles
  • Molecular geometry and polarity using
    electrostatic potential maps

CO2
H2O
8
Advantages to students
  • Compliments the good old
  • ball-and-stick molecular models
  • Enriched active learning environment
  • Compare virtual and tactual models
  • More complicated
  • structures

9
ChemSketch - classical 2D chemical structure
10
Classroom Activities
  • The World of Molecules (scroll down page)
  • Structure and Bonding
  • Discovering Intramolecular Interactions
  • Molecules in Motion
  • Studying Vibrations in Molecules

11
Online Instructor Resources
  • Interactive Visualization of Chemical Structures
    in Biology, Chemistry, and Geology Empowering
    Your Students with a Discovery Learning Tool
  • Teaching the Structural Nature of Biological
    Molecules Molecular Visualization in the
    Classroom and in the Hands of Students
  • Molecular Visualization A Microcosm of the
    E-Revolution
  • Molecular simulation What does my molecule look
    like?
  • Duane Sears biochemistry website
  • Some other useful instructional technology tools
