List of citizen science projects
|Part of a series on|
Citizen science projects are activities sponsored by a wide variety of organizations so average people can meaningfully contribute to scientific research. Activities vary widely from transcribing old ship logbooks to digitalize the data as part of the Old Weather project to observing and counting birds at home or in the field for eBird.  Participation can be as simple as playing a computer game for a project called EyeWire that may help scientists learn more about retinal neurons.
Lists of citizen science projects will change often. For example, the Old Weather project website indicates that as of[update] February 18, 2013, 12% of the logs (19,604 pages) were completed. When that project reaches 100 percent, it will move to the completed list.

- CosmoQuest is sponsored by NASA in partnership with the Astrosphere New Media Association, the STEM Center, UniverseToday, Astronomers without Borders, the Planetary Society, the Ward Beecher Planetarium, the Galileo Teachers Training Program, Swinburne Astronomy Online, Dark Skies, Bright Kids, the Canadian Astronomy Data Centre and its member organizations, the Galileoscope Project and several NASA projects.
- BirdSleuth is primarily for students from kindergarten through middle school.
- Formerly The Birdhouse Network which only monitored nests in bird boxes and similar artificial cavities. NestWatch is a new project that collects observations of open nests as well.
- Per the project website, this project was absorbed into the current FeederWatch project.
- Formerly Ice Hunters, a project to identify potential targets in the Kuiper belt for the New Horizons spacecraft after it completes its mission to Pluto.
- Over a million craters were identified and mapped in late 2012. As of March 2012, 1,207,486 craters have been identified and mapped by the Moon Mappers parent project that continues.
