Unplugged STEM Stations Pack 4: Cyber Security & Logic (Grades 4–8)

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 & Binary Logic! Designed for grades 4 through 8, this 10-page printable resource is completely unplugged—requiring zero computers or internet access for students—and engineered to run seamlessly as a 60- to 75-minute rotation lab, group workshop, or whole-class STEM activity.

What Is Included in This Pack?

• Page 1: Teacher Setup & Master Guide

  Contains a comprehensive materials checklist, a visual classroom station layout, prep steps, and 4 flexible implementation options for supplying 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 recording sheet for students to clip to a clipboard and carry from Station 1 to Station 5, keeping every team member accountable.

• Page 3: Station 1 Sign — Encryption Cipher Lab

  Hands-on cryptography station where students manipulate Caesar cipher wheels to encode secret messages using custom shift keys and decrypt incoming encrypted communications.

• Page 4: Station 2 Sign — Binary & Password Security

  Unplugged CS math station where students convert base-2 binary values into base-10 decimal numbers and perform combinatorial calculations to determine how long cracking algorithms take to break passwords of varying lengths.

• Page 5: Station 3 Sign — Network Data Packet Blueprint

  Technical drafting station where students construct schematic diagrams illustrating how data packets travel from source senders through network switches, routers, and firewalls to destination devices.

• Page 6: Station 4 Sign — Firewall Intrusion Detection Algorithm

  Unplugged algorithm station where students evaluate conditional flowchart decision trees (If/Then logic) to assess network packet security and select automated quarantine protocols.

• Page 7: Station 5 Sign — Real-World Case Study

  Informational reading station covering The Y2K Bug (Year 2000), examining legacy programming constraints, 2-digit year representations, and global software engineering prevention efforts.

• Page 8: Detailed Teacher Answer Key

  Provides fully worked binary conversions, password complexity math solutions, network blueprint checks, firewall logic keys, and case study reading guidance in clean plain text.

• Page 9: 10-Point Master Grading Rubric

  A single-page evaluation rubric scoring each station on a clear 0-to-2 point scale for efficient, consistent grading.

• Bonus Page 10: Caesar Cipher Wheel & Strip Templates

  Printable inner and outer alphabet rings and zero-assembly paper cipher strips ready to cut out and distribute immediately.
