The "Analog Project: Popsicle Stick Hexagons" is a 5-day engineering challenge designed for tweens to develop executive function skills through a structured manufacturing project. Over the course of 7.5 hours (1.5 hours per day), participants work to design and build a functional hexagonal structure, such as a display for socks or small ornaments.
The project progresses through the following phases:
Day 1: Planning — Define goals, brainstorm geometry, and create a resource list.
Day 2: Tooling — Design and build a jig for precision drilling and cutting.
Day 3: Production — Execute assembly-line production with quality control.
Day 4: Assembly — Build the 3D hexagonal structure and manage joints.
Day 5: Evaluation — Load test, present the process, and reflect on learnings.
Project Introduction & Resource Planning
Day 1
Goal: Understand the objective, explore design constraints, and audit the necessary materials.
Concept: Creative Exploration & Inventory Management. Before building, students must understand what resources are available and what the structural requirements are.
Activity:
Introduce the final goal: Building a scaled, functional hexagonal structure (e.g., a display for socks or small ornaments) with flat, stable sides.
Brainstorming session: How do we achieve a perfect hexagon? What geometric principles do we need to keep in mind?
Sketching designs and mapping out a master Resource List.

Tool Design & Jig Prototyping
Day 2
Goal: Solve the problem of replication and precision by building a manufacturing tool (the jig).
Concept: Mechanical Thinking & Process Optimization. Tweens tackle the executive function challenge of efficiency through planning.
Activity:
Problem Scenario: "How do we drill a hole in the exact same spot for 100 sticks, and how do we cut them perfectly in half without measuring every single time?"
Design the Jig: Use a combination of a thick foam pad and baseline popsicle sticks to create a rigid channel/boundary that holds a stick perfectly in place.
Create the Template: Glue a 1-inch metal washer directly onto a template popsicle stick to serve as a permanent, durable guide for the drill bit.
Stress Test: Test the jig by drilling and cutting a small batch (e.g., 5 to 10 sticks). Check for consistency by stacking them to see if the holes align perfectly. Adjust the jig if shifting occurs.
Mass Production & Quality Control
Day 3
Goal: Execute repetitive tasks efficiently and maintain quality across a large batch of materials.
Concept: Stamina, Attention to Detail, and Workflow Management.
Activity:
Set up an assembly line or production routine based on yesterday's successful jig prototype.
Process the remaining inventory: Drill the designated pivot holes and cut the required number of sticks perfectly in half using the jig guides.
Quality Control Check: Periodically stack processed sticks in groups of 10 to ensure the holes haven't drifted and the jig isn't wearing down.
Structural Assembly & Execution
Day 4
Goal: Translate the 2D planned design into a physical, scaled 3D hexagonal structure.
Concept: Spatial Reasoning, Adaptability, and Structural Integrity.
Activity:
Begin assembling the pieces using the fasteners through the pre-drilled holes.
Manage the flat sides of the hexagon, ensuring the joints pivot smoothly enough for adjustment but remain rigid enough to support weight.
Troubleshooting: Address real-time engineering challenges, such as pieces warping, joints loosening, or balancing the structure at scale.
Final Evaluation & Process Presentation
Day 5
Goal: Reflect on the project, test functionality, and communicate the manufacturing process.
Concept: Metacognition, Presentation Skills, and Practical Testing.
Activity:
Load Testing: Test the final structure's functionality by using it for its intended purpose—holding socks or hanging small ornaments.
The Process Display: Have the tweens organize a presentation showing their original Day 1 sketches, the Day 2 jig template, and a lineup of perfectly identical sticks to prove their system worked.
Reflection: Discuss what worked, what failed, how the jig saved time, and how they would change the design if they had to build it again.
