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.

Born to Engineer - Andrew Robertson

Andrew Robertson is a computer engineer working at Queen Mary, University of London on music signal processing. 

He has engineered a software package that allows bands to drive the tempo of their music to the response of the crowd and still keep their layered backing tracks in time with the beat. This film...

Bee-Bots Basics

This introduction to using the small programmable robot, the BeeBot, introduces children to creating simple programs. They learn the importance of sequences of accurate instructions, and test their sequences out using a 'fakebot' or paper-robot. Children are encouraged to debug and develop their sequences before...

Data Representation

The first video explains why computers use binary to store data.  The difference between a bit, nibble, byte, kilobyte, megabyte, gigabyte, terabyte and petabyte is explained.  These are known as measurements of capacity, or how much data can be stored either in memory or on secondary storage devices.

Translators and Facilities of Languages

The first video takes a brief look at the history of programming.  It examines the differences between low level languages such as Assembly, and high level languages such as Python.  It considers the uses of each of these different types of languages.

The second video we explain the purpose of translators...

Computational Logic

The first video explains why data is represented in binary using examples of RAM, a hard disk, optical disks and solid state memory.

The second video illustrates simple circuits built using components to create AND, OR and NOT logic gates.  GCSE students need to be able to combine gates to create more...

Producing Robust Programs

The first video is about defensive design considerations.  Data is not always entered in ways that a program might expect.  If this can be easily rectified without asking the user to re-input the data, it is known as input sanitation.  In addition, to prevent invalid data crashing a program, validation techniques...

Programming Techniques

The basics of programming are explored through a “beat that dice” game.  It is assumed that students already have some knowledge and experience of programming before watching the first video, and the purpose of this video is to marry the theory of programming to the established practical experience in preparation...
