Close Reading Mystery Text Evidence Inference Activity - Slime in the Hot Tub

Engage your students with a high-interest close reading and inference mystery that challenges them to analyze text evidence, think critically, and pay attention to important details. In this classroom investigation, students must carefully read a variety of texts, compare accounts, and identify inconsistencies in order to determine who filled the hot tub with slime. This close reading activity moves beyond surface-level comprehension and pushes students to make inferences and justify their conclusions using specific evidence. Designed for collaboration and discussion, this high-interest activity improves inference skills, critical thinking, close reading, and problem-solving, and encourages students to support every claim with text evidence.

Reading mystery back story: The Ooze family is hosting a little backyard get-together for Uncle Saul, who is visiting from out of town. When some of the family members jump in the hot tub at the end of the night, they immediately notice something is off. The hot tub has been filled with green sticky slime, and now they are covered in it. Your students need to figure out who’s responsible.

Included In This Close Reading and Text Evidence Inference Mystery Activity:

➡️ Inference Mystery Presentation Slides: This 15-slide PowerPoint presentation guides the entire inference mystery activity from beginning to end. It introduces the backstory, presents the evidence, and walks students through the final reveal. The slides help structure the inference mystery and provide clear explanations outlining why each suspect is innocent or guilty. The built-in answers make whole-class review simple and easy.

➡️ Classroom Poster: Use this eye-catching poster to immediately hook students as they enter the room. Posting it on your classroom door or board builds curiosity and sets the tone for the inference mystery activity before the lesson even begins.

➡️ Original Narrative Backstory: This short narrative sets the scene during the family gathering when the slime is discovered in the hot tub. Students learn about the event, who was nearby, and the unusual details surrounding the incident. The story establishes the timeline, introduces potential suspects, and provides essential background information students will reference throughout the investigation. Hidden clues and subtle hints are embedded within the narrative, requiring careful close reading and attention to detail.

➡️ A Variety of Clues and Evidence: Students examine a variety of evidence presented in realistic formats, requiring them to read carefully, compare details across sources, and piece together information to build a strong, evidence-based conclusion. The evidence includes a blog post, a text message, a poster for a candy store, an email, a scientific study report, an overheard conversation, and an epoxy information sheet. Each piece contains relevant details that may support or refute a suspect’s involvement. Students must use close reading and draw logical inferences based on what the texts reveal.

➡️ Text Evidence Graphic Organizer: This graphic organizer helps students track clues, record important details, and organize their reasoning during the inference mystery activity. Students list information they learn about the suspects, cite specific evidence, and explain how each clue supports or contradicts their theory. The organizer ensures conclusions are grounded in close reading and text evidence.

➡️ Teacher Answer Key: A detailed answer key is included in both printable format and embedded within the presentation slides. This allows for a dramatic whole-class reveal at the end of the investigation.

How The Close Reading and Text Evidence Inference Mystery Activity Works:

• Start the inference mystery activity by displaying the poster on your door to build anticipation. As students enter, place them into small groups so they can collaborate and begin working together to solve the mystery.

• Use the presentation slides to guide you through the introduction of the close reading inference mystery. The slides help you set up the backstory before they begin analyzing the evidence.

• Distribute the evidence to each group, giving students time to read carefully, analyze the details, make inferences, and locate specific text evidence that supports or refutes each suspect. Encourage discussion within groups as they compare ideas and build their case.

• Once each group has made a final prediction, use the presentation slides to reveal the culprit. Review each suspect one by one, walking through the evidence that proves their innocence or guilt so students can clearly see how strong text evidence leads to a logical conclusion.
  
  

What Teachers Are Saying About This Close Reading and Text Evidence Inference Mystery Activity:

⭐️⭐️⭐️⭐️⭐️ My students loved using this resource! I used it in a small group; it was great to use independently, with a small group, or with partners.

⭐️⭐️⭐️⭐️⭐️ This is a great resource to have students make inferences and prepare for higher level thinking.

⭐️⭐️⭐️⭐️⭐️ My students absolutely love these mysteries - the hot tub slime was a favorite so far. They love the "funny" topics and situations, and I love that they use inferencing skills and other ELA skills to help them figure out things on their own. My 6th graders tend to be a bit "needy" and want me to TELL them the answer, so these mysteries are a gem for helping them get to the answers on their own!
