Seeing Temperatures

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...

Building Images

In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

Dijkstra's Algorithm

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

Space Radiation

For teachers of advanced physics who may have an interest in computing, this Astro-Pi activity explores radiation in space and considers how it might affect human health. Humans currently live aboard the International Space Station, where they are exposed to radiation emanating from the Sun and from cosmic ray...

Magnetic Earth

This AstroPi resource helps secondary school students investigate the magnetic field of the Earth. The series of activities develops from basic principles of magnetism through to some understanding of the nature and cause of the Earth's magnetism.

The guide links to several other eLibrary resources and a...

Introduction to big data

A detailed presentation from Ben Houghton, data scientist at Barclays PLC. It is good introduction to Big Data and the three Vs (volume, variety and velocity). Other topics covered are machine learning and its use in fraud detection, legal and data privacy challenges and technology bottle necks caused by...

People like me mothers and daughters session

This session aims to help students to make career decisions, as they can think about how they will fit in when choosing their own future directions
The session highlights which job roles can suit individual personalities – these roles are not restricted to STEM industries but where STEM knowledge is...

Networks

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. *Explain what an IP...

Quantum Key Distribution

Produced in 2015, these resources look at the development of encoding messages and how technology and science has developed to allow us to keep messages secure. Looking at unintuitive quantum properties of light, Heisenberg’s Uncertainty Principal and entanglement, students will see how keys can be shared to...

The Intelligent Piece of Paper

In this activity from the CS4FN team, learners are introduced to algorithms in the context of artificial intelligence. They are challenged to beat a ‘piece of paper’ at a game of noughts and crosses. By following a simple algorithm, the piece of paper becomes very difficult to beat. The algorithm is a sequence of...
