Mission World Wide Web Lesson Plan

This curriculum-linked lesson plan is the feature of our safer internet activity - Mission World Wide Web!

If you haven't already - sign up to the activity here to get a free Mission Resource Pack which includes an A3 poster, stickers, 35 agent cards and a Detective Dot Adventure book for your class!*

The lesson plan is split into two 40 minute sessions. Lesson 1 explores how information is sent through the cables of the World Wide Web. Lesson 2 takes a look at how information is sent through the fungi network of the Wood Wide Web.

Together with Detective Dot (an agent for The Children's Intelligence Agency) pupils investigate the internet and it's natural equivalent to find the best method for top secret messages! This is done through the Connected Devices Activity in Lesson 1, which demonstrates how a message is sent and how devices are linked. Lesson 2 includes a simple scientific investigation into the wood wide web on school grounds or local green space! 

Learning objectives include:

  • To recognise that computers everywhere are all connected
  • To use technology safely, respectfully and responsibly and recognise acceptable/unacceptable behaviour
  • To understand computer networks including the internet; how they can provide multiple services, such as the World Wide Web; and the opportunities they offer for communication and collaboration
  • To plan an investigation
  • To record data accurately

The lesson plan is linked to the Mission World Wide Web assembly and related activity packs including an alternative for pupils with SEN.

Full curriculum links are listed below.


*Please note we have a limited number of our free Mission Resource Packs, they are given on a first come first serve basis for UK primary schools.

Mathematics and Numeracy:

  • I can solve practical problems by applying my knowledge of measure, choosing the appropriate units and degree of accuracy for the task. (MNU 3-11a)
  • I can use the common units of measure, convert between related units of the metric system (MNU 2-11 b)


Digital Literacy:

  • I can explore online communities demonstrating an understanding of responsible digital behaviour and I’m aware of how to keep myself safe and secure (TCH 2-03a)
  • I can keep myself safe in online environments and I am aware of the importance and consequences of doing this for myself and others. (TCH 3-03a)


Computing Science:

  • I am developing my understanding of information and can use an information model to describe particular aspects of a real world system (TCH 3-13b)
  • I understand how information is stored and how key components of computing technology connect and interact through networks (TCH 2-14b)
  • I can describe the structure and operation of computing systems which have multiple software and hardware levels that interact with each other. (TCH 3-14b)



  • I can relate physical and behavioural characteristics to survival or extinction (SCN 2-01a)
  • I understand how animal and plant species depend on each other and how living things are adapted for survival. (SCN 4-01a)






  • Transfer mathematical skills to a variety of contexts and everyday situations.
  • Select and use suitable instruments and units of measurement.
  • Estimate and visualise size when measuring and use the correct units.
  • Choose between metric units to measure a length (Y3)


Information and Communication Technology:

  • Produce and use models or simulations to ask and answer questions.
  • Share and exchange information safely through electronic means.
  • How to use ICT safely and responsibly, and to consider the hazards and risks their activities.



  • Opportunities to study, through fieldwork, the plants and animals found in two contrasting local environments (e.g. identification, nutrition, life cycles, place in environment)
  • Study the independence of living organisms in environments.
  • Study the environmental factors that affect what grows and lives in environments.


Northern Ireland 

Mathematics and Numeracy:
