Here’s an explanation of Citizen Science Month from CitizenScience.org:

In just a couple of years, Global Citizen Science Month (April) has grown from a single day of events, to a coordinated effort supported by SciStarter, the National Library of Medicine, Arizona State University, the Citizen Science Association, Science Friday, National Geographic and many other collaborators from around the world. Global Citizen Science Month encompasses online events and opportunities to contribute to projects from home.
