Simple Dynamic Models for Hydrogen Bonding Using Velcro-Polarized Molecular Models
Emeric SchultzJournal of Chemical Education2005 82 (3), 401Simple Dynamic Models for Hydrogen Bonding Using Velcro-Polarized Molecular Models
Emeric SchultzJournal of Chemical Education2005 82 (3), 401This article describes the use of models that dynamically illustrate the unique characteristics of weak intermolecular interactions, specifically hydrogen bonds. The models clearly demonstrate that H-bonds can break and reform while covalent bonds stay ...

Michael J. Sanger and Steven M. Badger IIJournal of Chemical Education2001 78 (10), 1412This study reports how instruction including visualization strategies associated with computer animations and electron density plots affected students' conceptual understanding of two chemistry topics. Two sets of students responded to several conceptual ...

Robert D. Curtright , Randy Emry , John MarkwellJournal of Chemical Education1999 76 (2), 249This exercise sets up a collaborative activity that challenges students to develop a chromatographic solvent with the appropriate polarity to separate leaf chlorophyll and anthocyanin pigments by TLC. The suggested activity has been tested with both high-...
