Martin Hollins (2006) explained an insight about national curriculum, the original focus on key stage 3 was because it was acknowledged as 'forgotten key stage'. It is an intermission time between crucial end of key stage 2 and most important key stage 4. The pupils fall back in their attainment during early parts of key stage 3. This results a new key stage 3 programme of study for science was introduced in 2007 which support the key stage 4 programme which released in 2004.In the new National curriculum for 14-16 years old in England this is called 'How Science works' and stated an importance of the process of science rather than the content. The other requirement of the programme is called the 'Breadth of study' and is a selection of key ideas from across the sciences: Biology, chemistry, physics, astronomy, earth and environmental sciences .The selection builds on the work in key stage 3 and is seen to be of current relevance to pupils personal wellbeing, their everyday life and the technological world they inhabit To meet the needs of those who intend to progress in their science studies beyond 16, there is a range of additional courses.
