Turn a digestive system maze into a hands-on STEM lesson. This guide shows parents and educators how to use the maze and working eye model from the STEM Science Kit for engaging human body science activities.

Quick Answer

Use the digestive system maze from the STEM Science Kit as a hands-on tool to teach kids how food travels through the body. Pair it with the working eye model for a complete anatomy lesson.

Why the Digestive System Maze Works for STEM

The maze turns an abstract biological process into a tangible puzzle. Kids physically guide a token through the digestive tract, which reinforces the order of organs and their functions better than a diagram alone.

A common trade-off is that younger children (ages 4-5) may need help with the maze's fine-motor demands, while older kids (ages 6-8) can complete it independently and explain each step.

Pairing with the Working Eye Model

The STEM Science Kit also includes a working eye model project. After the digestive system maze, building the eye model gives kids a second concrete example of how a body system operates, reinforcing the idea that organs work together.

This pairing works well for a 30-45 minute lesson: start with the maze, then build the eye model. It keeps kids engaged without overwhelming them.

How to Use the Digestive System Maze: Step-by-Step

Set Up the Maze and Explain the Goal: Place the maze board on a flat surface. Show your child the start (mouth) and finish (end of the large intestine). Say: 'We're going to move this token through the digestive system in the right order.' Common mistake: skipping the explanation. Without context, kids treat it as a random maze instead of a learning tool.
Guide the Token Through Each Organ: Have your child move the token from the mouth to the esophagus, then the stomach, small intestine, and large intestine. Pause at each organ to name it and say one simple function (e.g., 'The stomach mixes food with juices to break it down'). Checkpoint: If your child rushes, ask them to repeat the organ name before moving the token.
Discuss What Happens at Each Stop: After completing the maze, go back and ask open-ended questions: 'What do you think happens to food in the stomach?' or 'Why is the small intestine so long?' Let them guess before you confirm. Common mistake: turning it into a lecture. Keep it conversational so kids stay curious.
Repeat with the Working Eye Model: Build the eye model according to the kit instructions. Then compare the two systems: 'The digestive system processes food; the eye processes light. Both have parts that work together.' Checkpoint: Make sure the eye model pieces are assembled correctly before testing. Loose parts can frustrate kids.
Extend the Lesson with a Simple Drawing: After both activities, give your child paper and crayons. Ask them to draw the digestive system or the eye from memory. This reinforces what they learned and shows you what they remember. Common mistake: skipping the drawing. It's the best way to check understanding without a formal quiz.
