Encryption is the key to information security. The key to modern encryption is that using only public information, a sender can lock up their message in such a way that it can only be unlocked by the intended recipient. The resource begins with a detailed explanation of the activity and how the process of...

A 4-week lesson programme introducing robotics to KS3 using a Micro:Bit and a BitBot. The Bit:Bot Robot is easy to assemble and comes equipped with programmable neopixels, light and line following sensors.  This series of lessons introduce embedded programming, control structures, switching on the neopixels,...

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...

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 four instant maths ideas exploring how to represent data graphically. In the first task students record how long they watch TV, group the results and draw two separate graphs to compare boys and girls. The second task requires students to consider what type of diagram is suitable to represent...

This series of three lessons introduces Python programming to students in secondary school. The lesson objectives include:

• Creating simple code including the input and print scripts
• Using "If statements" to make a decision
• Using the random function in programs

Detailed...

The aim of this workbook, written by Ali Mulla, is to provide a simple introduction for students to programming in the language Python. The book contains examples, tasks for students to complete and space for students to write their observations and answers to questions posed. The topics covered are: dealing with...

This series of resources supports the teaching and learning of the computer programming language Python. The series of activities, produced by Code Club have support sheets for each of the activity projects. They are easy to follow and support progression in the learning. The activities require studenst to: *...

This activity booklet uses the real life context of air traffic control using radar signals to identify the position of an aeroplane that students act out. It provides them with an opportunity to use their knowledge of waves and speed = distance / time to calibrate and calculate the distance a plane is from the...

This resource supports students to research and discuss the field of robotics and artificial intelligence (AI). The resource provides a series of student tasks that explore the topic of whether robots are a threat to humanity. This resource would work well as a research topic for students undertaking projects in...

Artificial intelligence (AI) is a disruptive technology, meaning that it is significantly changing the way that people, businesses, and industry interact. To put it in context, the invention of the wheel, electricity, TV, and GPS are all disruptive technologies that changed the way in which society worked.

...

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

The joy and challenge of building ‘cheap and cheerful’ sensors has a wide appeal to adults as well as children. It also opens a wide number of links to aspects of the mathematics, science, computing, design and technology, and engineering curricula, supporting scientific investigation and discovery. These...

Cryptographic techniques enable information to be shared with other people, yet still maintain a surprisingly high level of privacy. This activity illustrates a situation where information is shared, and yet none of it is revealed: a group of students will calculate their average age without anyone having to reveal...

This resource contains ten instant maths ideas using spreadsheets to solve mathematical problems. Mathematical topics explored include: * solving equations to complete a think of a number puzzle * completion of magic squares * exploring different sequences * the ‘Rich Aunt’ problem * an exploration of cubic graphs...
