Affordable STEM Projects for Classrooms on a Budget

Bringing STEM into the classroom doesn’t have to mean expensive tools or complicated setups. With just a few low-cost materials and a little imagination, students can dive into real-world science and tech concepts — all while having fun. Here are some creative and affordable STEM project ideas you can try in your classroom: 1. Paper Circuits: Using copper tape, a coin cell battery, and an LED light, students can create glowing greeting cards or art. It’s a fun way to learn how circuits work — and costs under ₹30 per student. 2.
