Atoms are represente by large 1 1/4" and 1 1/8" colored enameled balls drilled to receive connecting bonds.  The bonds are represented by slotted pegs and springs, which make for easy assembly.  The kit is designed to demonstrated the nature of compounds the fundamental concepts of chemical change.  Students can visualize the three-dimensional structure of a molecule and see first-hand the signifigance of the formulas.

The materials in this kit can be used to construct many different organic moleculs and to illustrate different forms of isomerism, including structural isomers, cis-, trans-isomers, and chiral compounds.  For example, propyl and isopropyl alcohol can be readily distinguished, as can ortho, meta, and para substituents on a benzene ring.
