Rogue Rodent Mystery: A Crime Scene Investigation Classroom Kit

Engage your budding scientists with this intriguing mystery that really hits home when a beloved classroom pet Alice has gone missing. Your younger students can join the fun and learn all about crime scene investigation and help solve the Rogue Rodent Mystery!

Crime Scenario

A crime occurred in Ms. Hawkins’ science classroom at Cavia Elementary. Her classroom is filled with all sorts of neat things and also has a pet Guinea pig named Alice. Yesterday, Mrs. Hawkins said goodbye to her students as they headed home. She put Alice safely back in her enclosure and then went to the cafeteria to grab an afternoon snack. When she came back 20 minutes later she noticed…Alice was gone!

How It Works

To limit the suspect possibilities, Ms. Hawkins has narrowed the suspects to four—all current students of hers. Together, your students work toward the most plausible scenarios and celebrate their findings in the concluding lesson with certificates honoring their work as forensic investigators.

What's Included

The Classroom version of the Rogue Rodent Mystery includes a comprehensive 103-page Instructor's Guide, Introductory Video, and Teacher Resource Thumb Drive, which includes student handouts, a supply list, training tutorials, and the essential supplies to conduct experiments with your class.  

Preparing to Teach

Instructors will find The Rogue Rodent Mystery easy and fun to teach. Each lesson provides 1-3 activities that teach a new but related aspect of scientific reasoning and a particular scientific process. The text is easy to read and understand, the set-ups are detailed and uncomplicated, and the processes and procedures are clearly explained in each lesson plan.

Course Outline

The Rogue Rodent Mystery is comprised of 10 lessons, designed each to take approximately 1-hour, for a class of 30 students.

Lesson 1 - Observing the Clues: Investigation with Your Senses 

In this first lesson, your students are introduced to the mystery of the missing guinea pig through a video taken immediately after realizing that Alice was missing. Students will also be introduced to the job of a forensic scientist and prepare to take on the role by practicing their skill of observation.

Lesson 2 - Recording Your Findings: Sketching the Scene 

This lesson will challenge your students to make a rough sketch of a pretend crime scene. The focus of sketching at this stage (rough) should be the inclusion of all objects, the proper positional placement and relative size of objects in the scene.

Lesson 3 - Listening to a Witness: Creating a Composite Sketch

Students will discover that a picture can replace a long verbal description and help others better understand. In science it is very common to use pictures - photographs, diagrams and graphs – to convey your process and findings.

Lesson 4 - Analyzing Alibis: Monitoring the Movement of Suspects 

In this activity, students will hear the alibis of four suspects. They will practice the skills of a forensic scientist by listening carefully to each story. Then, using matching picture cards, students will retell the details of each suspect’s story in sequential order.

Lesson 5 - Applying Physics: Studying Force and a Falling Skeleton

Students will focus on the fallen model skeleton in Mrs. Hawkins’s classroom to imagine (and predict) what happened on the day Alice was taken. By running a simple experiment, students will make a connection between a force (a rolling ball) and the resulting movement of the object (a model skeleton).

Lesson 6 - Inspecting Pattern Evidence: Comparing Shoe Prints 

For this lesson, students will focus on visible, two- dimensional prints. They’ll study the visible, two-dimensional shoe prints left behind on Mrs. Hawkins’ classroom floor. Students will try to match parts of a print to a larger pattern and measure the length and width of the shoe print.

Lesson 7 - Researching Rodents: Discovering a Guinea Pig’s Survival Needs

Students will be asked to learn more about guinea pigs to better understand how Alice came to be missing. Is it possible that a suspect took Alice home? This information will be recorded in a table. Students will use the table to make arguments about the potential involvement of each suspect.

Lesson 8 - Following Colorful Clues: Making Orange Paint 

In this activity, students will figure out which suspect was most likely to have left behind orange paint smudges by mixing together different primary colors of paint. Students will be challenged to follow a procedure in the correct order.

Lesson 9 - Weighing the Evidence: Testing the Scales of Justice 

Students will use balances to literally weigh the evidence of each suspect against one another. Not only will this give your students a chance to use a common measurement tool in science, it will provide a visual to help them formulate their own conclusions.

Lesson 10 - Considering the Confession: Understanding Misunderstandings! 

This last activity is designed to tie together any loose ends or resolve unanswered questions about the mystery. It is also designed as a celebration of the mystery solved!
