The Case
A rare fossil has gone missing, and a line-up of suspects is waiting. The only way to crack the case is to read closely about the types of fossils — how they form and what they tell us about the past — using every comprehension answer as a clue to rule a suspect out, until just one remains.
How the Reading Mystery Works
Students step in as Reading Detectives, reading about the types of fossils and knocking a suspect off the list with each text-based answer until the culprit is cornered. The answers are all in the passage.
