The Case

Something has gone wrong at the molecular level, and a line-up of suspects is waiting. The only way to crack the case is to read closely about DNA — its structure, replication, protein synthesis, and mutations — using every comprehension answer as a clue to rule a suspect out, until just one explanation fits the evidence.

How the Science Mystery Works

Students work as Science Detectives, reading about DNA structure and function and clearing a suspect with each text-based answer until the culprit is all that's left. The answers are all in the passage.

How Reading Mysteries Work

Each Reading Mystery resource gives you five one-page cases that turn close reading into a clue-based investigation. Here's exactly how a case plays out.

Case Briefing

Every set turns reading practice into a case to crack

Students step into the role of Reading Detective. They read closely, pull evidence straight from the text, and use it to rule out suspects — one clue at a time — until only the culprit is left.

THE EVIDENCE BOARD · 4 STEPS TO CRACK IT
01

Read the Passage

Each case opens with a short, themed reading passage that sets the scene and names what's gone wrong.

Hooks them fast
02

Hunt for Text Evidence

Students answer comprehension questions — and every answer is a clue pulled straight from the words on the page.

Close reading
03

Work the Suspect Line-Up

They match each clue against the suspect board and cross off names. A wrong answer points to the wrong suspect — so it self-checks.

Self-checking
04

Name the Culprit

One suspect is left standing — and students crack the case. The reveal makes review feel like a win, every time.

Why Teachers Use Reading Mysteries

Skill practice that feels like a case worth solving — and a download that quietly does a lot of your planning for you.

Why teachers keep their students on the case

5 cases per set 0 prep or setup Color & black-and-white Answer keys included

Builds Real Close Reading

Students must return to the text and use evidence to answer — so they're practising comprehension, inference, and text-evidence skills, not just guessing.

Self-Checking by Design

The right answers rule out the right suspects, so accuracy matters — and the included answer keys mean there's nothing for you to grade.

Hooks Reluctant Readers

The whodunit format gives even hesitant readers a reason to keep going. Reading practice starts to feel like a game, not another worksheet.

Truly No-Prep

No cutting, laminating, apps, or logins. Print in color or black-and-white and hand them straight out — that's the entire setup.

Fits Any Routine

One case as a warm-up, or spread five across the week for centers, partner work, early finishers, sub plans, or intervention.

Differentiation-Friendly

Great for on-level practice, an extension for advanced readers, or a targeted review pass for anyone who needs another go at the skill.
