Unplugged STEM Station Pack 4: Cyber Security, Encryption & Binary Logic 4th–8th

Bring hands-on cyber security, cryptography, binary math, network architecture, and unplugged computer logic into your classroom with STEM Station Pack 4: Cyber Security, Encryption & Unplugged Coding! This 9-page printable resource is completely unplugged—no computers or internet required for students! It is designed to run smoothly as a 60- to 75-minute rotation lab using basic classroom supplies. 📦 WHAT IS INCLUDED IN THIS PACK? Page 1: Teacher Setup & Master Guide Includes a master materials checklist, classroom station map, setup instructions, and 4 flexible options for providing cipher wheels (including printable cardstock templates, DIY paper plate wheels, or zero-assembly paper strips). Page 2: Student Answer Sheet (1-Page Master Handout) A single, organized handout for students to clip to a clipboard and carry from Station 1 to Station 5. Keeps every student accountable! Page 3: Station 1 Sign — Encryption Cipher Lab Students use a Caesar cipher wheel to encrypt secret messages with custom shift keys and decode incoming coded messages. Page 4: Station 2 Sign — Binary & Password Security Students convert binary values into decimal numbers and calculate the exponentially growing time required for computer algorithms to crack passwords of varying lengths. Page 5: Station 3 Sign — Network Data Packet Blueprint Students draw a technical schematic showing how data packets move from senders through routers and firewalls to receivers. Page 6: Station 4 Sign — Firewall Intrusion Detection Algorithm Students trace a conditional flowchart (If/Then logic) to evaluate network traffic and select automated security responses to isolate malware. Page 7: Station 5 Sign — Real-World Case Study Students read a technical passage on The Y2K Bug (Year 2000), learning about legacy code constraints, memory limits, and preventive engineering. Page 8: Detailed Teacher Answer Key Includes fully worked binary conversions, password math solutions, blueprint checks, firewall logic responses, and case study guidance in clean plain text. Page 9: 10-Point Master Grading Rubric A criteria-specific rubric evaluating every station on a 0-to-2 point scale for quick and consistent grading. 🎯 LEARNING OBJECTIVES & ALIGNMENT NGSS MS-ETS1-1, MS-ETS1-2: Engineering Design & Failure Prevention CSTA 1B-AP-10, 2-AP-11: Unplugged Algorithms, Encoding, and Cyber Security Concepts CCSS.MATH.PRACTICE.MP1 & MP4: Binary Base-2 Math & Combinatorial Calculations 🛠️ MATERIALS NEEDED Paper cipher wheels, brass paper fasteners (optional), pencils, paper, and basic calculators.
