April is Citizen Science Month! In celebration, we will be highlighting one citizen science project from NOAA and our partners from now until Earth Day on April 22. NOAA engages the public in support of key mission areas through the rapidly growing field of citizen science — a form of open collaboration in which individuals and organizations participate voluntarily in the scientific process. Citizen scientists take part in a range of activities from observing precipitation type and amount to helping map the ocean floor. Whether trekking out to local beaches to count horseshoe crabs under a full moon or measuring Earth’s magnetic field from a smartphone, citizen scientists support NOAA’s mission while learning more about the world around them. Check back daily Monday through Friday for new projects that you can explore! You can also follow the countdown on social media — we're @NOAAeducation on Facebook, Twitter, and Instagram.
