Encryption Basics
👩🏫 Teacher’s Guide
Objective
Students will explain encryption as a way to protect information by turning it into secret code and identify simple uses like secure messages and passwords.
Teaching Notes
- Explain encryption as scrambling information so only the right person can read it.
- Use a simple cipher example (shift letters) for demonstration.
- Connect to HTTPS and secure messaging in a kid-friendly way.
- Emphasize that encryption helps protect privacy and safety.
