Interlocking Toy Building Blocks as Modules for Undergraduate Introductory and General Chemistry Classroom Teaching
Samuel Melaku, Rajeev B. Dabke
Abstract
Interlocking toy building blocks (e.g., Lego) as chemistry teaching modules are presented. Interlocking building blocks were assembled on a baseplate to depict chemistry concepts of Lewis structures, chemical bonding, conjugate acid–base pairs, types of chemical reactions, irregularity in ionization energy trends, and the decay of a radioactive isotope. The modules were presented to visualize these chemical concepts in undergraduate introductory and general chemistry classrooms. Modules were presented on a document camera in an online mode of delivery.
