Claims are cheap. Here is the work.

Grade 8 · Science

“Can we build an air purifier that actually works — and prove it?”

A DIY purifier tested against five hypotheses, with CADR, CFM, static pressure and PM2.5 all measured. Having built a working machine, the learners were then made to argue how it could still fail: too noisy, too costly to maintain, impossible to repair locally, dependent on a filter nobody nearby stocks. The three-fan configuration and the open, repairable body were their own decisions.

Later taken out of school to a university Department of Electrical Engineering. Written up by Krishna Purohit, facilitator — including the measurements that contradicted the team’s first idea.

Grade 10 · Enterprise

“People sort waste wrongly. Can you remove the decision instead of teaching it?”

SegreSmart — a bin with a sensor module mounted on the central divider that makes the wet-or-dry decision for the user. Dry on one side, wet on the other.

Pitched nationally at LaunchVerse, August 2026, among India’s Top Schools.

Grade 10 · Enterprise

“Does sound change how fast microbes grow?”

An incubator with built-in music at set frequencies to aid microbial growth. Filed as a patent through the Summer Patent School at Shoolini University — prior-art search, AI tools, the legal framework, all of it.

The programme supplied the mechanism. The question was already hers, from earlier work on microbial growth.

Grade 9 · Design

“Design a chair. Then actually build it.”

A chair, made in a carpenter’s workshop with real tools and real consequences.

It came apart in the workshop and stayed in pieces for ten minutes. Priyanka Kaur Oberoi, who set the assignment, published an account of exactly that — because that was when the learning happened.

Grade 5 · Civic

“What is actually wrong in your own neighbourhood?”

The Noida Project — every learner identified a problem they had personally observed, and wrote to the District Magistrate about it.

The unit was designed around field visits. Extreme heat made stepping outdoors impossible and they were cancelled. Nandini Singhal published that account too.

Grade 8 · History

“Whose Renaissance was it?”

A decentring of the standard Eurocentric account, built from primary sources rather than a textbook summary.

Written up by Vidya Viswanathan, facilitator.

Grade 5 · Language

“What is a poem for?”

A poetry unit that had to be abandoned and restarted.

The facilitator’s carefully prepared scaffolds produced a room of compliant, disengaged children. She published that under her own name. A school where an adult can write that down is a school where a twelve-year-old can say it too.

Grade 7 · Purpose

“Can a toilet work without water?”

A waterless toilet, working as a demonstration model.

A stationary installation remains at feasibility stage. Purpose Projects reliably produce good prototypes and unreliably produce implementations, and we would rather say so.

Grades 8–10 · Dialogue

“Can you argue a position you disagree with, properly, before you answer it?”

Hocokah 2026 — Socratic dialogues with seven participating schools. No winner is declared.

Built on purva-paksha: state the other position properly first.

Grades 11–12 · Career

“What happens when the work has consequences outside school?”

Discovery Projects, Guilds and internships — seven named senior-school placements with a partner organisation, a workplace, an examiner, a public.

The point is the consequence, not the certificate.

Middle · Outdoor

“What can you only learn by leaving?”

Majkhali — a rural immersion, written up by the two facilitators who ran it.

Kavita Tiwari and Mohit Kwatra, November 2024.

Grade 11 · Arts

“Photograph something true.”

Selected by open call into a twenty-project international children’s exhibition at the Chennai Photo Biennale, alongside work from the UK, Turkey, Guatemala, South Africa, Cambodia and Gaza.

Open call. Not an invitation, not a school quota.
