ClueSpark field guide
An expanding archive of science, math, and history investigations. Browse the subjects, then open a downloadable case file when it is ready for your verdict.
Archive protocol
Topic cards map the full investigation archive. “In the archive” means a subject is being researched—not yet a finished download.
Planetary evidence
Trace the forces that shape water, land, and the living worlds caught between them.
Atmospheric evidence
Read the atmosphere like a case report: pressure, heat, motion, and change over time.
Cosmic evidence
Follow light, gravity, and time across the universe—from nearby worlds to its first moments.
Living evidence
Investigate the systems that build bodies, behavior, memory, culture, and everyday life.
Pattern evidence
Use mathematical tools to test theories, uncover patterns, and make a defensible case.
Historical evidence
Compare sources, artifacts, fossils, and records to ask how we know what we think we know.
Available case files
These live case files come directly from the ClueSpark catalog. More subjects will move from the archive when their investigations are complete.
