April is Citizen Science Month!
A global celebration of public participation in scientific research.
Each April, Citizen Science Month celebrates the people, projects, and scientific outcomes made possible through public participation. In 2026, we are also working together toward a shared goal of 2.50 million Acts of Science, marking America’s 250th Birthday through collective discovery, service, and impact.
Anyone can participate. No prior experience is needed. Every contribution counts.
No need to wait until April! Citizen science happens all year long. Join SciStarter to discover ongoing projects and receive updates about Citizen Science Month.

What Is an Act of Science?
An Act of Science is a real contribution to scientific research. During Citizen Science Month, every time you participate in a citizen science project, such as classify an image from camera trap footage, or attend a citizen science event, you are doing Acts of Science.
The goal of 2.50 million Acts of Science is a shared, collective goal, highlighting how millions of small actions, taken together, can accelerate scientific research and improve our world.
