How to Use Chemistry Mystery Games to Make Review Engaging and Effective

Making Chemistry Review Engaging and Interactive

Traditional study methods, like reading textbooks and completing worksheets, often struggle to hold students' attention. Research shows that active learning strategies, such as problem-solving, collaboration, and movement, are far more effective in helping students retain key concepts.

One way to make chemistry review more engaging and interactive is by using chemistry mystery games. These whodunit-style activities combine critical thinking, problem-solving, and core chemistry skills, allowing students to apply their knowledge while unraveling a mystery.

In this blog post, I’ll show you how to implement a chemistry whodunit game in your classroom, making chemistry review both fun and academically meaningful while reinforcing important concepts like balancing equations, periodic trends, and reaction types.

What Is a Chemistry Whodunit?

A chemistry whodunit is an interactive classroom activity where students investigate a crime, mystery, or missing artifact while applying chemistry concepts. Each game presents a narrative-driven scenario, and students must solve the mystery by answering chemistry-related questions.

Similar to Clue™ (Cluedo™), students are responsible for determining the perpetrator, the crime scene, and the method used, using scientific reasoning and logic to arrive at their conclusions.

This approach is particularly effective because it:

✔️ Engages students by embedding chemistry concepts within a compelling storyline.

✔️ Encourages critical thinking as students analyze clues and draw logical conclusions.

✔️ Makes abstract concepts more tangible by applying them in a real-world problem-solving context.

✔️ Promotes collaboration when played in teams or pairs.

How to Implement Chemistry Mystery Games in Your Classroom

Chemistry mystery games can be adapted to different learning formats, ensuring that all students stay engaged while reinforcing high school chemistry concepts. Whether you have a full class period or need a shorter review session, here’s how to effectively integrate this activity into your curriculum.

Setting the scene for the chemistry whodunit focused on balancing chemical equations

Step 1: Identify your learning Objectives

Before implementing a whodunit game, clarify the learning goals.

• What chemistry concepts will students be practicing?

• How does the game align with NGSS standards and classroom objectives?

  
  

You can introduce the whodunit game in two ways:

1. At the beginning of a unit – As an introductory activity to spark curiosity and build foundational knowledge.

2. At the end of a unit – As a review activity where students apply what they have learned.

For example, my Solve the Mystery Chemistry Whodunit Games focus on specific chemistry topics, such as:

• Periodic Table Trends

• Balancing Chemical Equations

• Types of Chemical Reactions

• Moles and Stoichiometry

• Significant Figures and Measurements

• Atomic Structure and Electron Configuration

Selecting a targeted chemistry concept ensures that the game directly reinforces key content.

Step 2: Set the Scene – Capturing Student Curiosity

Before students dive into answering chemistry questions, they need context for the mystery.

You can introduce the case in several ways:

• Read a crime report aloud – Describe the mystery in detail to build suspense.

• Hand out police reports and suspect profiles – Let students familiarize themselves with the characters.

• Post the backstory on your class website – Emailing students the crime report the night before builds anticipation.

  
  

💡 Tip: Treat the mystery like a real investigation! Encourage students to take notes and discuss theories before beginning the chemistry portion.

Police report for Alan Turing showing the possible weapons and Possible location of the crime

My students always look forward to receiving a police report or a newspaper article before class, introducing the mystery we will investigate. When they arrive, I distribute a police memorandum that includes descriptions of potential suspects, weapons, and locations—similar to the Clue™ game setup.

Stage 3: Distribute Evidence- The Chemistry Connection

Now that students understand the mystery, it’s time to introduce the chemistry challenge.

• Each piece of evidence relates to a chemistry concept (e.g., reaction types, balancing equations, atomic structure).

• Correctly answering chemistry questions reveals clues, bringing students closer to solving the case.

• Students record their deductions in an evidence log, tracking which suspects, locations, and weapons they have eliminated.

  

  
  

💡 Optional: Start the lesson with a quick bell-ringer review to refresh students’ knowledge before they begin solving the mystery.

Stage 4: Encourage Movement – Turning the Classroom into a Crime Scene

Engagement increases when students move around the room rather than sitting at their desks..

• Set up 12 “evidence stations” – Each contains a different chemistry-related question or clue.

• Students rotate between stations (individually, in pairs, or small groups).

• No strict order – Allow students to work at their own pace to prevent bottlenecks.

• Use a timer – This keeps energy levels high and maintains momentum.

  
  

💡 Alternative Setup: Instead of stations, hand out an envelope with all clues to each group and let them work collaboratively at their desks.

For added immersion, you can decorate the classroom with crime scene tape or use mystery-themed sound effects.

Stage 5: Verify Their Findings – Checking for Accuracy & Reflection

Once students have worked through all evidence, they must submit their conclusions.

✔️ If correct, they confirm that all chemistry answers are accurate and have solved the case.

✔️ If incorrect, guide them to find their mistakes:

1. Backtracking: Encourage students to revisit their clues and identify errors.

2. Answer Key Review: If short on time, provide the answer key for self-assessment.

   

   
   

💡 Final Reflection: To reinforce learning, I provide a final police report detailing:

• The culprit

• The motive

• The evidence used to solve the case

• 
  

This gives students a sense of closure while reinforcing the chemistry concepts they applied.
