Inside the case file
Investigate the planet we call home. This printable Planet Earth Reading Mystery turns a nonfiction passage about Earth into a reading-detective investigation for Grades 3–6 classroom teachers, homeschoolers, and tutors. It drops straight into an Earth science, space, or geography unit and hooks students into reading for the evidence.
Students comb the text for evidence, cross suspects off with each answer, and race to name the culprit — all print-and-go.

The Case
Something is not right across the planet, and a line-up of suspects is waiting. The only way to crack the case is to read closely about Planet Earth — its layers, its land and water, and the atmosphere that surrounds it — using every comprehension answer as a clue to rule a suspect out, until just one remains.
How the Reading Mystery Works
Working as Reading Detectives, students read about Planet Earth, answer to gather evidence, and clear a suspect with each correct answer until the culprit is cornered.
