Subject: Information Communication Technology ICT
Lesson Topic: Know and understand solid-state media including memory cards (SD, xD, CFast)
Learning Objective/s:
  • Describe what solid‑state media are and their advantages over magnetic media.
  • Identify the main types of memory cards (SD, microSD, xD, CFast) and their typical capacities and uses.
  • Explain speed classes and how to match card speed to device or video requirements.
  • Evaluate factors for selecting an appropriate memory card for a given device.
  • Apply safe handling and data‑backup practices for solid‑state cards.
Materials Needed:
  • Projector or interactive whiteboard
  • Sample memory cards (SD, microSD, xD, CFast)
  • Laptop with card reader
  • Printed worksheet/handout with comparison table
  • Whiteboard and markers
  • Anti‑static sleeves (optional demonstration)
 Introduction:

Begin with a quick poll: “What storage device do you use most on your phone or camera?” Connect this to prior knowledge of flash drives and highlight that memory cards are a form of solid‑state media. Explain that today’s success criteria are to describe the types, compare capacities and speed classes, and demonstrate safe handling.
Lesson Structure:
  1. Do‑Now (5') – Students list storage devices they have used and share responses on the board.
  2. Mini‑lecture (10') – Define solid‑state media, discuss advantages, and show a diagram of an SD card.
  3. Card comparison activity (15') – In groups, examine sample cards and complete a worksheet comparing capacity, size, speed class, and typical uses.
  4. Speed‑class demonstration (10') – Play short video clips, match required bitrate to appropriate speed class, and discuss implications.
  5. Choosing the right card scenario (10') – Case‑study worksheets where students select a card for a specific device/task.
  6. Data safety practice (5') – Demonstrate safe removal, use of anti‑static sleeves, and regular backup; finish with a quick quiz.
  7. Recap & Q&A (5') – Review key points and answer remaining questions.
Conclusion:

Summarise that solid‑state memory cards provide fast, durable storage and that selecting the right card depends on capacity, speed and device compatibility. Ask students to write one tip for safe handling on an exit ticket. For homework, they should research the recommended card for a device they own and bring their findings to the next class.
