Design and Practice of Chemical Science Popularization Experiments Based on the Concept of Controlling Variables: Taking the “Recovery of Silver from Silver-Containing Wastewater” Science Popularization Project as an Example
Abstract:
Science popularization activities should not only disseminate scientific knowledge but also promote scientific thinking methods. This study explores and implements chemical science popularization activities that embody these scientific ideas and methods. Using the project “Recovering Silver from Silver-Containing Wastewater” as an example, we briefly introduce the implementation of an engaging science popularization activity plan centered around the concept of controlling variables. This approach aims to enhance the public’s understanding of controlling variables through three levels: recognizing scientific variables, understanding the method of controlling variables, and experiencing the application of this concept. This progression ultimately aims to improve scientific literacy. Additionally, discussions on the toxicity and pollution of silver-containing wastewater, along with recovery and treatment methods and their values, foster the public’s awareness of green environmental protection and the principles of resource recycling.
