EarthCache
A free, worldwide geology-focused offshoot of geocaching, developed with the Geological Society of America. Participants use GPS coordinates to visit geologically significant real-world sites, answer earth-science questions about what they observe, and can complete self-paced EarthCache Academy lessons on topics like geologic time, fossils, and earthquakes.
Weather Archive Africa (Zooniverse Citizen Science)
A virtual citizen-science project where volunteers help digitize and quality-check historical African weather station records from paper archives, supporting climate change research across 43 African countries. Students transcribe station names, dates, and readings, and flag damaged documents.
Earth Science Week Contests (AGI)
Annual national contests held during Earth Science Week (mid-October), sponsored by the American Geosciences Institute. Students enter the photography, video, visual arts, or essay contest with work tied to that year's Earth Science Week theme.
Mountain Rain or Snow
NASA- and Desert Research Institute-backed citizen science project (started as Tahoe Rain or Snow) where volunteers text or use a web app during winter storms to report whether precipitation is rain, snow, or a mix, helping researchers improve mountain precipitation forecasting models used across the Sierra Nevada and other US mountain regions.
Raspberry Shake Schools Program
Schools purchase a low-cost Raspberry Shake seismometer package to install on campus, giving students hands-on experience collecting real-time seismic data (from footsteps to real earthquakes) and joining a global citizen-seismology station network with free data and software tools.
AGU Bright STaRS
American Geophysical Union program inviting middle and high schoolers worldwide to present original Earth and space science research, including earthquake and seismology topics, as a poster at AGU's Annual Meeting, with complimentary conference registration included.
