Grade: Date: 17/01/2026
Subject: Computer Science
Lesson Topic: Show understanding of the differences between the World Wide Web (WWW) and the internet
Learning Objective/s:
  • Describe the role of the Internet as the global networking infrastructure.
  • Explain how the World Wide Web operates as an application‑layer service on the Internet.
  • Compare key characteristics (OSI layer, core protocols, purpose, components) of the Internet and the WWW.
  • Identify common misconceptions about the relationship between the Internet and the WWW.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Printed comparison‑table handout
  • Laptops/tablets with internet access
  • Web browsers (Chrome/Firefox)
  • Sticky notes for exit ticket
 Introduction:

Begin with a quick poll: “Which online services do you use every day?” Capture responses on the board, then ask students to consider what underlying system makes all those services possible. Review the previous lesson on basic networking concepts and state that today they will be able to distinguish the Internet from the World Wide Web and explain why the distinction matters.
Lesson Structure:
  1. Do‑now (5 min): Students list as many online services as they can; share a few examples.
  2. Mini‑lecture (10 min): Define the Internet and the WWW, show a layered diagram, highlight OSI layers and core protocols.
  3. Guided analysis (12 min): In pairs, students complete a partially‑filled comparison table, then discuss differences.
  4. Misconception check (8 min): Present three common misconceptions; students vote true/false using clickers and justify their choices.
  5. Interactive demo (10 min): Open a website, use browser developer tools to view HTTP headers and discuss how the WWW sits on top of the Internet.
  6. Formative quiz (5 min): Quick Kahoot/exit‑ticket with 2‑3 questions to assess understanding.
Conclusion:

Summarise that the Internet is the global packet‑switching infrastructure, while the WWW is a specific application that delivers hypertext via HTTP/HTTPS. Students complete an exit ticket: write one sentence distinguishing the two and name another Internet service (e.g., email). For homework, they will draft a short paragraph comparing the Internet and the WWW and list two non‑web services that also rely on the Internet.
