Small Steps, Big Impact

Teamwork that takes us further

Echelon is the V-shaped formation birds use when migrating. Birds at the back conserve energy before taking their turn to lead the pack. This teamwork is what we hope students will emulate through Echelon, our technology fest.

The theme for every event this year is “Small Steps, Big Impact”. Interpret it any way you want—be creative. Students in Grades 8–12 come together at Bangalore International School, in collaboration with Vidyashilp University, to turn small ideas into meaningful results.

  • Eight ways to compete

    Escape a locked room, find treasure, design websites and games, build with e-waste, race drones, pitch innovations and create an expert system in SWI-Prolog.

  • Teams from your school

    Like migrating birds sharing the lead, work together, support your teammates and build on one another’s ideas.

  • One day on campus

    Everything happens at Bangalore International School, from 8:15 am to 2:30 pm. Breakfast and lunch are provided.
