Earthworms

Inside the case file

Dig up the clues. This printable Earthworms Reading Mystery turns a nonfiction passage about nature's little engineers into a reading-detective investigation for Grades 3–6 classroom teachers, homeschoolers, and tutors. It drops straight into a life science, soil, or animals unit and makes close reading the whole point.

As students work the questions, the suspect list shrinks — reading carefully is the only way to reach the answer. Just print and hand it out.

The Case

Something is at work beneath the soil, and a line-up of suspects is waiting. The only way to crack the case is to read closely about earthworms — how they live, what they eat, and how they keep soil healthy — using every comprehension answer as a clue to rule a suspect out, until just one remains.

How the Reading Mystery Works

Students take on the Reading Detective role, reading about earthworms and using every text-based answer to eliminate a suspect until one remains.
