Very simply, this involves making sparkles flash. The challenge is to work out how long a ‘dot’ and a ‘dash’ are, and to successfully code a message in Morse code.

This resource provides an overview for a lesson where students in Year 7 choose a blogging platform (if they are allowed to choose for themselves this comparing and contrasting the various offerings could be a lesson in itself), and set up a blog. They are also given various prompts to help with evaluating what...

This Challenge Pack, from the British Science Association, aims to give students aged 11-16 and their teachers and educators support to create a science, technology, engineering or maths (STEM) project that they can enter into the National Science + Engineering Competition.

Through creating a project, young...

A short unplugged activity. This uses string and various other props to enable students to simulate the various network topologies required for GCSE Computing. The activities lead naturally into discussions around protocols, data collisions and reliability. A large open area may be required depending on the size...

This series of five one-hour lessons covers computer networks at secondary-school level. The objectives of the lessons are:

• Describe what a network is, the difference between a LAN and a WAN and identify three network topologies.
• Describe pieces of hardware that are needed in a network.

This resource contains some rules for an unplugged networking activity to model how routers and networks deal with transmitting packets of data. The activity is designed for 6 people to act as routers, who apply the routing rules to packets of data. There are 4 end points which send and receive packets according to...

This presentation includes a number of topics on Networks and HTML, and includes various exam questions and other activities for students to complete. The presentation covers a wide range of network related topics, briefly covering: Network Types, Media, Topology, Protocols, Handshaking, Transmission, TCP/IP and...

A scheme of work which although aimed at the upper end of Key Stage 2, is also suitable for delivery at the bottom end of Key Stage 3.

Students would find this Computing at School community resource useful as a revision resource for the topics of networks and the internet. It is suitable to be issued as a sequence of homework tasks.

Using LDRs and sparkles, the student learns how to code a nightlight coming on only once it gets dark. Digital switches can also be incorporated into this.

Normalisation of floating point binary numbers is usually a topic where students require practice. This pair of documents explain the technique and then provide a set of questions with answers for independent working.

Another great resource from the Computing at School community which is suitable as a consolidation activity for small groups, designed to consolidate learning regarding converting positive integers between the binary, denary and hexadecimal number...

GCSE Computing – The Teacher’s Unofficial Guide This guide, which supports the OCR GCSE, covers how to teach the course. Separate sections look at: • Written examination • Practical investigation • Programming project It is not officially linked to the exam board, but they have ‘adopted’ it as their official,...

Greenfoot is an object oriented programming language based on Java. This resource uses a skeleton crab game program to teach the principles of Greenfoot programming. Students complete the activities to complete the program. The resource includes a greenfoot project and a completed project. These are aimed at...
