Microscale and Green Chemistry Initiatives at CCL, IIT Gandhinagar
At the Chemistry Lab in CCL, IIT Gandhinagar, we are reimagining chemistry education through microscale and green chemistry approaches that make learning hands-on, safe, and sustainable. Recognizing the persistent challenges in chemistry teaching—limited resources, lack of infrastructure, and passive learning—we focus on developing low-cost, eco-friendly experiments for middle and high school that encourage students to explore science actively and meaningfully.

Our flagship initiative, “Chemistry in a Box,” introduces over 50 simple, safe, and engaging microscale experiments that bring chemistry concepts to life. These activities use very small quantities of chemicals, following green chemistry principles that minimize waste and environmental impact while maximizing learning. Students learn to think like scientists, investigate real-world phenomena, and connect textbook concepts to their daily lives. For testing and improving Chemistry Kits, we have established CTAB (Chemistry teachers Advisory board),a group of 11 teachers (from govt and private schools) who provide valuable feedback on the usability and relevance of CCL’s kits and manuals. Their insights ensure the kits are practical, effective, and classroom-ready across diverse educational settings.
