Soya chunks-bamboo toothpick molecular model: An Eco-friendly model for Chemistry teaching in resource-limited settings

Abstract

Physical and computer models are frequently used at all levels of science teaching. In emergency and resource limited environments an affordable, easy to implement, and environmentally friendly model would be important for effective teaching. Here, we report on a homemade ball-and-stick type molecular model made from soya chunks and bamboo toothpicks. We implemented the model for high school and graduate level Chemistry teaching both in online and classroom environments. The end semester survey (n=206) showed the model is easy to use and made learning easier. Our study suggested that the model can be an effective and ecofriendly alternative to teach some of the difficult-to-understand topics in Chemistry and related disciplines in resource limited settings.
