Subject: Information Communication Technology ICT
Lesson Topic: Know and understand the uses of wi-fi and Bluetooth
Learning Objective/s:
  • Describe the basic principles and frequency bands of Wi‑Fi and Bluetooth.
  • Compare the range, speed, power consumption and typical uses of Wi‑Fi and Bluetooth.
  • Identify advantages, disadvantages and security best practices for each technology.
  • Evaluate appropriate real‑world applications of Wi‑Fi and Bluetooth.
Materials Needed:
  • Projector or interactive whiteboard
  • Laptop with internet access
  • Wi‑Fi router and Bluetooth‑enabled devices (smartphone, headphones)
  • Printed comparison handout/worksheet
  • Diagram of Wi‑Fi and Bluetooth networks
  • Whiteboard markers
 Introduction:
Begin with a quick poll: how many students use Wi‑Fi at home and Bluetooth with headphones. Review that they already know basic wireless concepts from previous lessons. Explain that today they will explore how these technologies differ and when to choose each, with the success criteria of being able to compare features and suggest suitable applications.
Lesson Structure:
  1. Do‑Now (5') – Students list devices they use daily that rely on Wi‑Fi or Bluetooth.
  2. Mini‑lecture (10') – Explain Wi‑Fi fundamentals (frequency, range, standards) using slides.
  3. Mini‑lecture (10') – Explain Bluetooth fundamentals (frequency, classes, versions) with a live pairing demo.
  4. Comparison activity (15') – Pairs complete a Venn‑diagram worksheet comparing features, then discuss findings.
  5. Application brainstorming (10') – Groups choose everyday scenarios and decide which technology is best, presenting to the class.
  6. Security quick‑check (5') – Short quiz on WPA3 and Bluetooth pairing safety (Kahoot or show of hands).
  7. Recap & exit ticket (5') – Students write one key difference and one security tip on a sticky note.
Conclusion:
Summarise that Wi‑Fi provides high‑speed, longer‑range connectivity for network access, while Bluetooth offers low‑power, short‑range links for peripherals. Ask students to share one new insight they gained. Collect exit tickets and assign homework to research a new Wi‑Fi or Bluetooth device and note its specifications.
