Representations

Representations Screenshot

Chemists have developed advanced written notations to convey the structure of molecules. Although the symbolism represents only the connectivity of the atoms, these impoverished representations imply the specific geometry of the molecule.

Representations trains students to relate the notation of the impoverished drawing with the richness of the three dimensional structure of the molecule. Random presentation of a variety of impoverished drawings, typical of textbooks, are compared with three-dimensional models of rotating molecules drawn using advanced lighting and rendering techniques. The models may be correct or may include logical but incorrect interpretations of the drawing. Students identify the accuracy of the model and receive corrective feedback if appropriate.
