Global Citizen Science Month Expands with European Collaboration
Participatory science gains traction; researchers aim for more than 1,000,000 Acts of Science this April during Citizen Science Month
This April, Citizen Science Month goes global like never before! SciStarter.org, Arizona State University, and partners are once again calling on people around the world to contribute to more than 1,000,000 Acts of Science—but this year, the European Citizen Science Association (ECSA) is bringing a powerful new dimension to the movement.
ECSA is taking to social media to spotlight citizen science projects and engagement opportunities across Europe and the UK, amplifying the collective impact of volunteers worldwide. With a growing number of international participants, Citizen Science Month 2025 is set to be the most globally connected edition yet, uniting schools, libraries, federal agencies, associations, community-based organizations, and individuals in an unprecedented push for participatory science.
A true international movement
Last year, more than half a million volunteers from 126 countries contributed to over 1,000 projects and events, with participation happening organically rather than through a coordinated international effort. This year, thanks to the strengthened partnership with ECSA and other global networks, the effort will be more intentional in its outreach, engaging participants in diverse scientific research that matters.
Here's how to get involved:
Visit CitizenScienceMonth.org – Whether you want to participate, help others get involved, or showcase your own project, there’s a way for everyone to engage.

Report your Acts! – Log your Acts of Science on CitizenScienceMonth.org before April ends. Track global participation and celebrate when we reach one million!
Science without borders
From classifying galaxies in Dark Energy Explorers to monitoring biodiversity through iNaturalist, volunteers worldwide will engage in projects that contribute meaningful data to scientists. Many projects require only a smartphone, making participation accessible to all. Throughout the month, researchers will share outcomes made possible by volunteers, showcasing the tangible impact of global citizen science efforts.
Building a global community
The expanded international scope of Citizen Science Month 2025 includes collaboration from participatory science associations across Europe, Africa, Asia, Australia, and South America. ECSA’s leadership in highlighting EU and UK-based projects will ensure that more people than ever before can find meaningful ways to contribute to science and policy through citizen science. Moreover, the D-A-CH working group promotes Citizen Science Month on social media in Germany, Austria, and Switzerland.
Paul, an engagement specialist at the Northeast Wisconsin Land Trust, reflected on the power of global participation: “When it comes to conservation, we talk about the need to ‘think globally, act locally,’ and participation in events like Citizen Science Month helps us do just that!”
Join the movement at CitizenScienceMonth.org to participate, support research, and help us reach One Million Acts of Science in April 2025!
This media toolkit provides sample social media posts and other resources to promote the event.
About SciStarter
SciStarter is a research affiliate of the School for the Future of Innovation in Society at Arizona State University. It provides a free web platform that connects scientists with volunteers from all walks of life. SciStarter connects millions of people to thousands of scientists in need of their help. SciStarter partners with a thousand libraries, museums, school districts, Girl Scouts, Verizon and many other organizations to train, guide and support community participation in projects and to measure and share individual and collective impact through sophisticated data analytics. SciStarter is supported by federal agencies including the National Science Foundation and NASA, the NNLM All of Us Program Center, private foundations, school districts and universities, Verizon and the Girl Scouts USA, making it possible to offer free access to a searchable database of projects and events, trainings, curated experiences, and personalized data dashboards to track participation across websites and apps.
