Celebrate America250: Join 2.5 Million Acts of Science this Citizen Science Month

Libraries, museums, and other community spaces are cornerstones of civic life and curiosity. In April 2026, they’ll become launchpads for discovery—inviting individuals and families to join citizen science projects that spark imagination and advance real-world research.

In celebration of America’s 250th Anniversary, join a movement that highlights the power of everyday people to shape our future through science. Be part of America Gives and America Innovates by participating in the “2.50 Million Acts of Science“ challenge throughout April 2026—Citizen Science Month!

From birdwatching and testing water quality to classifying galaxies at the library, people of all ages in your community can make a difference. As we celebrate America’s 250th birthday, we’ll honor a legacy of discovery—and spark its future—one act of science at a time.

Preparing for America250 with SciStarter

With support from Arizona State University and SciStarter, anyone can contribute to real scientific research by sharing observations, uploading photos, analyzing data, and more—all through simple, meaningful activities in your own community. Visit SciStarter.org/250 (coming soon) to find a project that fits your interests and schedule.

Through three phases—Inspire & Listen, Equip & Prepare, and Act & Celebrate—you’ll prepare for April using free resources, trainings, examples and support.

Timeline: Fall 2025 (September-December)

Goal: Build excitement and awareness around citizen science while connecting to local values, interests, and history.

Examples:

  • Host displays, tabling events, or short programs introducing citizen science. Find resources here.
  • Share stories about historical figures who practiced science (e.g., Benjamin Franklin, Indigenous observers, community health workers).
  • Hold a community listening session or use survey templates to gather input on local priorities (e.g., environment, health, history).
  • Use tools like My Wish for the U.S., OnOur250th.org, or story mapping to gather hopes for the future.
  • Invite local leaders, elders, or youth to co-lead conversations.

How SciStarter Can Help: 

  • Provide ready-to-use materials (flyers, posters, bookmarks) to introduce citizen science to your patrons.
  • Host monthly Citizen Science Month: 2.5 Million Acts of Science planning calls. 
  • Promote your activities via the SciStarter events page

Timeline: Winter 2026 (January- March)

Goal: Get ready! Train staff and volunteers, select citizen science projects, and prep your space and schedule. This phase ensures everyone has the skills, tools, and confidence to take action together—fostering local ownership and sustainability.

Examples:

  • Complete the Foundations of Citizen Science and SciStarter Ambassador trainings and share it with staff and volunteers.
  • Choose projects from SciStarter or your state’s A250 priorities (e.g., pollinators, air quality, local weather, health).
  • Download or request free toolkits, guides, or activity kits. Find resources here.
  • Identify dates and formats for events in April–July (single events, series, tabling, etc.).
  • Connect with SciStarter Ambassadors or nearby library teams for co-planning.

Timeline: Spring/Summer 2026 (April – July)

Goal:  Engage your community in 2.5 million Acts of Science—then celebrate the impact.  This phase transforms inspiration and preparation into meaningful action—reminding all Americans that participation is patriotic, and science is a tool for building a better tomorrow.

Examples:

  • Host one or more citizen science events during Citizen Science Month (April)—from Moth Nights to weather monitoring to local history documentation.
  • Add your events to SciStarter.org/add-event to have your events featured.
  • Encourage patrons to log their “Acts of Science” on CitizenScienceMonth.org
  • Share updates and photos on social media using #America250 #ActsofScience.
  • Celebrate with a showcase event in June or early July: share data collected, display art or stories from participants, and reflect on what was learned.
  • Offer certificates or recognition for local contributors.

How SciStarter Can Help: 

  • Feature your events in national calendars and help you log them toward the 2.5 million Acts of Science goal.
  • Provide printable and digital celebration materials—including participation certificates, signage, and social graphics.
  • Share an “Impact Tracker” dashboard so you can see and share your contributions in real time.
  • Support you with event-day troubleshooting, reminders, and recognition tools
