International Day of Women and Girls in Science
The International Day of Women and Girls in Science is observed each year on February 11. It celebrates the contributions of women in science and encourages girls to explore scientific learning and careers. The day also draws attention to the barriers that can make it harder for women and girls to take part in science on equal terms.
How the day started
The United Nations General Assembly proclaimed February 11 the International Day of Women and Girls in Science. The observance is supported by the United Nations and its organizations, including UNESCO and UN Women. Its purpose is to promote access to and participation in science for women and girls.
The day is not a public holiday. It is an international observance that brings schools, community groups, scientific organizations and individuals together to recognize achievements and encourage more inclusive opportunities in science, technology, engineering and mathematics.
Why women and girls in science matter
Science helps people understand the world and address challenges in areas such as health, food, energy and the environment. When people with different experiences and perspectives can contribute, they can ask a wider range of questions and bring fresh ideas to their work. Making room for women and girls in science is part of ensuring that talent and curiosity can flourish.
Women have contributed to many scientific fields, yet their achievements have not always received equal recognition or been included in accounts of scientific history. The day offers a chance to learn about their work, celebrate role models and make visible the many paths into science. It also highlights the importance of supportive classrooms, mentors, fair opportunities and workplaces where people can develop their skills.
Science is not limited to laboratories. It includes asking questions, observing carefully, testing ideas, solving problems and learning from results. Those habits can be part of everyday life, as well as careers in fields such as medicine, astronomy, engineering, computing, agriculture and conservation.
Ways to take part
- Meet a scientist. Look for a local library, school, university or science center hosting a talk or activity. If there is no event nearby, watch an interview or read a profile of a woman working in a field that interests you.
- Explore a hands-on activity. Try a simple experiment at home, build a paper structure, observe the Moon, or start a nature journal. Choose an activity that fits your age group and follow safety instructions.
- Share a role model. Tell a child or friend about a woman scientist, engineer or inventor. You might choose someone from your community, a historical figure, or a person whose work connects with a shared interest.
- Visit a science space. Spend time at a museum, planetarium, botanical garden or nature center. Ask questions, try interactive displays and notice the range of subjects that science can involve.
- Encourage curiosity. Make space for girls to ask questions, experiment and make mistakes without feeling they need to have every answer. Offer a science book, kit, class or outing as a way to keep that curiosity growing.
- Support inclusive learning. Ask a school or community group how it encourages girls to participate in science activities. Helping promote welcoming events and equal access can make a difference beyond February 11.
