Laboratory experiment design: Integrating silica gel for hands-on learning in water treatment and environmental stewardship

This study emphasizes the importance of laboratory work by using an unknown chemical in high school and university chemistry courses. It explores the use of silica gel in desiccant bags for water treatment as a cost-effective and educational tool, emphasizing environmental stewardship. The research targets high school and university students, demonstrating silica gel’s effectiveness in removing dyes and heavy metal ions from water and its potential use in sustainable construction materials. Pedagogically, the study aims to enhance students’ comprehension of environmental chemistry and sustainability through hands-on, problem-based learning. Safety considerations and innovative teaching methods are integral to the laboratory experience. The research illustrates the practical application of scientific knowledge in addressing real-world environmental challenges, promoting a circular economy, and inspiring sustainable practices in scientific education.
