Concord Consortium: Stem Resources: Molecular Geometry

For Students 9th - 10th
Students work through animated models showing the effects that electron repulsions have on the shape of a molecule in this web-based activity. In addition, shared and unshared electron pairs are demonstrated to define a molecule's shape....

University of Colorado

University of Colorado: Ph Et Interactive Simulations: Molecule Shapes: Basics

For Students 9th - 10th
Students studying molecule shapes will better understand its concepts with this virtual experiment that tests how a molecule's shape changes due to repulsions between atoms. Learning is further enhanced by building molecules in 3D.

Washinton University: Vsepr

For Students 9th - 10th
This site from the Department of Chemistry at Washington University is a nice site in that it gives you a graphical look at the arrangement of electron pairs. The plug-in CHIME will let you see the 3-D molecules, but it is good even if...
