Haunted House Cell Theory Color by Code | Halloween Science Activity

Looking for a practice activity that also incorporates a festive brain break without taking a lot of prep time? Want a Halloween science activity that is actually connected to your curriculum? Make cell theory review a little more spooky this October with this engaging Haunted House Color by Code Activity! Designed for middle school and high school biology students, this Halloween science activity gives students repeated opportunities to practice essential cell theory concepts while creating a fun haunted house scene.

Students solve each cell theory question, find their answer on the color key, and then use that color to shade the corresponding question number on their selected haunted house. With 4 different haunted house coloring options, students can choose their favorite design while practicing important biology content.

The activity comfortably combines content review, active recall, visual representation, and repeated practice in a format that feels more like a Halloween activity than traditional review. Perfect for Halloween week, October review, biology bell ringers, science centers, independent work, or a fun cell theory practice activity!

Why Teachers Love It

• Low-Prep: Print and go—no complicated setup required.
• Meaningful Practice: Students repeatedly retrieve and apply cell theory concepts instead of simply coloring.
• Visual Learning: Students connect their answers to a visual haunted house representation, giving them another way to interact with the content.

• Flexible: Use it for independent practice, review, early finishers, bell work, science centers, or a Halloween lesson.
• Built in student choice: Includes 4 haunted house coloring options so students can select the scene they want to complete.
