Biennial Event

The next ETH Biennial Event will take place in November 2026.

This event combines entertainment and practical activities for girls aged 11 to 14 years old, or 8P and CO, living in Geneva and the surrounding area. Around forty activities will be presented by women working in the fields of science, technology, engineering and mathematics (STEM) in French and English. Thanks to the generous support of our sponsors, all activities and lunch are free!

At each event, we welcome around 400 girls, who will choose from around twenty workshops and visit around twenty stands. The event will be filled with activities designed to inspire girls and show them that science and technology can be fun and interesting.

Information for workshop leaders

Every year we look for new workshops to offer. Workshop leaders play an important role in ETH's biennial event by sharing their personal stories with the girls and guiding them through hands-on activities to help them see that careers in STEM are exciting and within reach.
