Organic compounds, Lewis structures, and VSEPR theory are topics that challenge many tactile learners and are often supported using molecular models. Each style of molecular modeling come with different strengths and shortcomings. Line drawings provide a two-dimensional visual representation of molecular backbones but leave many students with an impression that molecules are static and retain set shapes. Many molecular modeling kits offer three dimensional models with an ability for students to rearrange the molecule while retaining bond lengths and angles. Incorporating primary literature research on the constructed molecules allows for learners to discover that such models lack an ability to demonstrate bond lengths, bond strengths, intramolecular bonds, and intermolecular bonds while opening an opportunity for conversations on such topics. Allowing for learners to construct their own models from found materials as an extension activity offers an opportunity for creativity in trying to communicate the characteristics that the learner deems most important.<br/>This presentation will focus on the use of molecular modeling activities at an engineering university and a community college. Applications in science major courses, non-science major courses, and using the different styles of modeling will be discussed. Examples of learner constructed models with found material will be supplied along with data collected on the impact of such modeling activities on lecture assessments.
