Practical information for monthly activities

About once a month we offer science activities or visits in the Geneva area. These activities usually take place on Wednesday afternoons or Saturdays. They are generally offered to girls between 10 and 18 years of age. For some activities, the age range may be restricted depending on the subject matter.

Come discover the work of an air traffic controller, fly drones in a wind tunnel, or simply discover the mathematics involved behind baking a cake!

For the adults: Become an EYH member and you will be amongst the first to be informed of these activities. The girl's you sponsor will be able to participate in these activities for FREE and will be entitled to priority registration... see more benefits in the member information page.
