We are on a mission to show every single girl that STEM was made for them too.

It all started with a single email and a simple question: is there something we need to do to encourage girls in science? The answer was a resounding yes, and it hasn't stopped echoing since.

What began as a conversation between fewer than 100 people has grown into a global community of scientists, engineers, teachers, coders, students and dreamers. We are all working towards one thing: making sure no girl decides STEM isn't for her before she's had the chance to try it.

Who we are

greenlight for girls (g4g) is an international non-profit headquartered in Brussels, Belgium, and registered in both Belgium and the US. Since 2009, we've partnered with companies, universities, schools, museums and community groups to give girls real, hands-on experiences in science, technology, engineering and maths. Our calendar now spans more than 100 cities on six continents.

What we do

We make STEM something girls can touch, build, test and laugh about. We don't lecture from the front of the room; we hand girls the pipette, the soldering iron or the robot controller. Every g4g experience pairs girls with real people working in STEM. It sets them loose on an experiment and sends them home with proof that they can do it. Our events are always free for girls to attend, so cost is never the reason a girl misses out.

Why the daisy

Look closely at the centre of a daisy and you'll find a hidden maths lesson. Its tiny florets grow in two sets of spirals, one turning clockwise and one counter-clockwise. Count each set and you'll almost always land on two neighbouring Fibonacci numbers, like 21 and 34.

Then there's the simpler reason. Ask almost anyone what the first flower they ever drew was, and the answer is usually a daisy. It's the flower of childhood doodles and daydreams, from the years before anyone tells you what you can and can't be. That's exactly the feeling we want every girl to hold on to: science is hers to explore, and anything is possible.
