This multimedia lesson for Grades 7-8 features eight animations and a hands-on lab to explore the role of valence electrons in covalent bonding. The multimedia approach provides an opportunity to visualize the attractions between atoms that result in covalent bonds. The lab investigation uses a 9-volt battery, alligator clips, and pencils to show how electrical energy can break the covalent bonds in water molecules. Editor’s Note: Covalent bonding occurs when electrons are shared between atoms; ionic bonding occurs when electrons are transferred between atoms. The processes are quite different. This module very effectively explores both formation and breaking of covalent bonds. Allow two class periods.
