By the time most students are in Year 7 they are extremely familiar with using computers for entertainment, research and school work. However, very few will have given the computer itself much thought. It is unlikely that they will know the origins of the first electronic computer or how computers have developed over the decades. Although they might have heard of the term, ‘transistor’, very few will know their role or how their development has been predicted by Moores’ Law. Even less will know about how computers process data and switch between tasks whilst working. And whilst they are familiar with the term, ‘software’, do they really know what it means? This scheme of work aims to provide a gentle introduction for students to the world of computers and computing
