Description
Summary:The authors describe the construction and use of tactile models for demonstrating intermolecular forces. These models are composed of inexpensive materials and can be used in college chemistry classrooms of varying levels including general and organic chemistry. The models were designed to be paired with an accompanying activity to encourage students to compare and contrast the three types of intermolecular forces (hydrogen bonding, dipole–dipole forces, and London dispersion forces) as well as determine the relationship between intermolecular forces and the physical properties of specific molecules. More importantly, the handheld models allow for visualization of molecular interactions to promote multisensory learning. In this work, the authors discuss the development, implementation, and survey results of a modeling activity for conceptualization and review of intermolecular forces in introductory, general, and organic chemistry classrooms.
