Molecule Building Lab

Added by Purnima Cheruvu on January 23, 2020

Molecule building lab allows students to apply octet rule in their effort to build molecules. Students first build Lewis models of their atoms and then bring the atoms together by sharing electrons to create molecules. The Lewis models of atoms are based on Lewis dot diagrams. These molecules are synthesized using marshmallows and skewers. In addition, students draw structures of molecules (just as it looks) and determine chemical formula as well as chemical name. As an extension, they are asked to translate their diagrams into Lewis structures of molecules.
