ABOUT CITIZEN SCIENCE MONTH

ANYONE, anytime, from anywhere, can be involved in Acts of Science each April during Citizen Science Month.

Individual acts add up to an important collective impact that accelerates scientific research, discoveries, and local actions that make a difference.

In April 2025, half a million volunteers from 100+ countries contributed more than Three Million Acts of Science through nearly 1,000 scientific research projects and events in April. That’s almost triple what we accomplished in April 2024!

From sharing photos of nature to help communities, planners, and scientists document biodiversity, to browsing images on your computer to help speed up research about Alzheimer’s disease, to using your phone to help track microplastics and air quality, each of these Acts of Science is important.

SciStarter helps connect people to projects and events all year long, but during Citizen Science Month, we work with many partners to reach people we’re not reaching throughout the year. Too many people are unaware that they are both needed and invited to take part in helping to shape the future through science.

During events, and anytime in April, everyone, everywhere, is encouraged to participate in projects. No prior experience is required.

WHAT IS AN ACT OF SCIENCE?

Attend an online or in-person event or join a project to play games that accelerate medical research, analyze online images to help make discoveries, share pictures of nature to help scientists spot biodiversity trends, use your smartphone to monitor your environment…and much more! These all count as Acts of Science!

With your help, we aim to make a collective impact of Millions of Acts of Science during Citizen Science Month. Our goal for April 2026 is to generate over 2.50 million data points to citizen science projects on SciStarter.org.

HOW DO I GET STARTED?

We’ve made it easy for you to join in! Visit CitizenScienceMonth.org to find ways to participate, whether that be by choosing a project to try out independently or attending an event online or in person near you. For a full list of projects, curated for the region you live in, visit our project finder. If you participate in a SciStarter Affiliate project, your Acts will automatically count toward the Acts of Science Tally in April.

THE HISTORY OF CITIZEN SCIENCE MONTH

Since expanding Citizen Science Day into Citizen Science Month in 2020, we’ve continued to grow and evolve. Along the way, we’ve developed foundational training to support both citizen scientists and facilitators, welcomed global partners to join the movement, and expanded our library network to create a thousand community hubs for citizen science around the world. Each April, we’ve pushed the boundaries of what citizen scientists can achieve—shining a spotlight on projects of all kinds and celebrating collective impact.

In 2024, for example, our partners Unique Mappers of Nigeria contributed 19,000 Acts of Science to a project using Open Map Data to help governments and humanitarian organizations better respond to vulnerable flood-prone communities. In 2025, 425 events were registered—ranging from one-hour sprints to multi-day efforts—resulting in project leaders reporting a surge of new energy and participation in their work.

Beyond the numbers, summative evaluation conducted by Arizona State University’s CREST Team in 2024 found that participants, project scientists and facilitators all benefit from Citizen Science Month and SciStarter’s support, from increasing understanding of citizen science, to feeling more confident in engaging in projects, to better understanding how people from all walks of life can play an active role in science, it’s clear that Citizen Science Month makes a difference.

Founding PARTNERS

SciStarter.org is the place to find, join, and contribute to science by providing people access to more than 2,000 searchable formal and informal citizen science research projects and events. The SciStarter website also offers a dashboard or coordinated place for members to track and earn credit for contributions across citizen science projects and platforms. More than 200,000 people are registered members of the SciStarter community. The SciStarter team includes educators, faculty, librarians, programmers, instructional designers, communicators, and scientists, all focused on improving the citizen science experience for everyone.

Arizona State University School for the Future of Innovation in Society (SFIS) is a transdisciplinary unit at the vanguard of ASU’s commitment to linking innovation to public value. SFIS pursues a vision of responsible innovation that anticipates challenges and opportunities, integrates diverse knowledge and perspectives, and engages broad audiences. By examining the ways we translate imagination into innovation — and how we blend technical and social concerns along the way — SFIS aims to build a future for everyone

Thanks to support over the years from the National Institutes of Health, the National Library of Medicine, and the Gordon and Betty Moore Foundation, SciStarter and Arizona State University have scaled the program globally, supported a network of more than 1,000 public libraries, and increased the public’s awareness of and engagement in scientific research.

FREQUENTLY ASKED QUESTIONS

What is Citizen Science Month?

Citizen Science Month is a celebration of citizen science each April. Citizen Science Month is an annual event to celebrate and promote all things citizen science: amazing discoveries, incredible volunteers, hardworking practitioners, inspiring projects, and anything else citizen science-related! Next Citizen Science Month, April 2026, we are aiming for a collective impact of 2.5 Million Acts of Science and we want you to be a part of it! Find a ton of online events and projects at CitizenScienceMonth.org!

Why do scientists want my help?

Scientists can’t be everywhere and they don’t know everything. That’s why they need you. You can help collect and share data and observations (for scientists who need data), or analyze online pictures or audio/video files (for scientists who have too much data). By following protocols, you can jump in and help answer questions they cannot answer without you.

Can I do citizen science outside of April?

Yes! We do citizen science every day, year round! April is simply a time to engage as many people as possible and invite them to join the community. CitSciMonth coincides with Earth month and Astronomy month, making it a very powerful time to be active in science.

Are there any special tools or technology needed for data collection?

You will likely need internet access and some device to upload your data (mobile device, tablet or computer), but most citizen science projects can be done without any special tools. If there is a required tool, the project pages on SciStarter will list the required tools or materials. This might be a mobile app, or a physical device, such as a rain gauge or special sensor.

Where can I find resources for putting on an event?

I still have questions! Who can I reach out to?

We’d love to hear from you! Email info@SciStarter.org. Also consider reaching out to a nearby SciStarter Ambassador.
