A 10-page unplugged STEM rotation pack on Caesar ciphers, binary math, password security, network blueprints, firewall algorithms, and Y2K case studies.
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 10-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: Master materials checklist, classroom station map, setup instructions, and 4 flexible options for providing cipher wheels (printable templates, DIY paper plate wheels, or zero-assembly paper strips).
Page 2: Student Answer Sheet (1-Page Master Handout): Single, organized handout for students to clip to a clipboard and carry from Station 1 to Station 5.
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 time required for 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 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: Fully worked binary conversions, password math solutions, blueprint checks, firewall logic responses, and case study guidance.
Page 9: 10-Point Master Grading Rubric: Criteria-specific rubric evaluating every station on a 0-to-2 point scale for quick grading.
