Celebrating National Science Day.
Shortlisted finalists present at IISc Bengaluru.
Free to enter.
For the student who asks one question too many: a national stage, a day at the Indian Institute of Science,
and the chance to discover what they are capable of.
STEMXplore started in 2022 as an online stage for students to explain science in their own words. It is now a two-day national symposium at IISc Bengaluru, run by STEMonsters — first principles, hands-on, inquiry-led.
Paper Electronics (ages 9–14) in the morning, Reverse Engineering (all ages) after lunch, and a webinar for parents and teachers — all on the IISc campus.
Three national competitions for Grades 4–12. Enter online by 14 February; shortlisted finalists present to the judges at IISc.
Free to enter from anywhere in India. Finalists present at IISc.
A 3-minute talk on a STEM idea you find fascinating — explained so clearly that a classmate, a parent and a professor would all learn something. The original STEMXplore event, now in its sixth year.
Build a working model that solves a real problem — and tell the story of how you got there: the need you noticed, the science you used, the versions that failed. Judges score the journey as much as the device.
Imagine a small everyday problem — a heavy schoolbag, a shelf you can't reach, a door that slams — and solve it with a cardboard prototype that uses a lever, pulley, wheel & axle, inclined plane, wedge or screw.
Both days happen on the campus of the Indian Institute of Science — India's foremost research institution.
How to get there →The first in-person finale, hosted at the Indian Institute of Science with IEEE PES and SPS Bangalore as partners. Let's Talk STEM, Story Behind My Tech, the STEM Lab Contest and a Jr. Hackathon — whose winning entry came from Singapore. Judges from IITs, GE Aerospace and IIM Bangalore.

The Bangalore Chapter of the IEEE Power & Energy Society brings judges, mentors and technical guidance to the competitions and workshops.
India's foremost research institution hosts both days of STEMXplore 2027 on its Bengaluru campus.
Bring your students to the competitions, run in-school rounds, and be showcased as a partner school.
Students in Grades 4–12, from any school in India or abroad. Competitions by grade band: STEM Lab Challenge 4–6, Let's Talk STEM 6–12 (Junior 6–8, Senior 9–12), Story Behind My Tech 7+. The Workshop Day is open to anyone who registers.
Competitions are free at every stage; outstation finalists have travel reimbursed on proof. The Workshop Day has a ₹99 token registration per student, which goes towards seats for partner schools. The webinar is free.
Let's Talk STEM is individual. The other two are team events for up to 4 students within the grade band. Teams with girls get bonus points in Story Behind My Tech. One student may enter more than one competition.
Finalists announced on 21 February are invited to IISc on 21 March. Travel is reimbursed against tickets; details come with the invitation. Under-18s must be accompanied by a parent, guardian or teacher.
Registrations open in November 2026 on this page — one form for students, one for parents and teachers (webinar). Schools: WhatsApp +91 97411 65171.
