🎯 Learning Intention

I will analyze how GPS technology works and discuss the ethical impact of global reliance on satellite data.

✅ Success Criteria

• I can summarize how satellites, timing, and triangulation work together.
• I can identify one ethical issue or risk tied to global GPS use.

☀️ Warm-Up (5 min)

“If GPS signals were suddenly encrypted again and civilians couldn’t access them, what industries would be affected first?”

🧠 Mini-Lesson (15 min)

• Brief recap of Real Engineering video concepts.
• Highlight the dual-use nature of technology (military origin → public benefit).
• Discuss data ethics: dependence, accuracy, security.
• Introduce term GNSS (Global Navigation Satellite System) – GPS, Galileo, GLONASS, BeiDou.

🛠 Independent Work (25–30 min)

• Students finish answering the 5 video questions.
• Add a short reflection: “What responsibilities come with controlling global systems like GPS?”
• Begin building a one-slide summary visual (title: GPS: Precision and Power).
