With rapidly evolving technology, the world is more connected than ever, and citizens around the globe can contribute to science like never before (Dickinson and Bonney 2012). Reflecting the growing capacity of citizen science, this article presents a science education continuum that moves from global awareness to global contribution. At each stage of the continuum, the authors provide examples of citizen science projects that educators can use or adapt to meet the needs of their students. Educators can enter the continuum at any stage they deem useful. Citizen science can engage learners in science while immersing them in science content and scientific practices. Participation in citizen science projects can foster science literacy, skill development in science communication, collaboration, critical thinking, 21st-century skills, and problem solving, and immerses participants in the open-ended nature of science experiences (Bonney et al. 2009). Citizen science projects can even happen on a global scale.
