Citizen science refers to a form of public participation and contribution in scientific research, where members of the general public voluntarily contribute their time, resources or skills towards observing, collecting data, reporting sightings or carrying out experiments. This type of collaboration between scientists and non-professionals allows for increased accessibility to scientific knowledge, while also providing opportunities for education, awareness, and engagement in environmental issues. Citizen science projects can range from simple observations such as counting birds or recording weather patterns, to more complex tasks like identifying galaxies or analyzing soil samples. The data collected through citizen science initiatives often supplements traditional scientific research methods, providing valuable insights into various ecological and environmental phenomena.
