Hodder Science Gold is a sister series to the highly successful KS3 Science series Hodder Science launched in 2000. The new series consists of three Pupil's Books aimed at pupils working between National Curriculum Levels 2 and 4/5. The three books comprise the same ideas and concepts as the mainstream Hodder Science books, enabling the two series to be used side-by-side in mixed-ability classes. The Gold books have, however, been rewritten and redesigned so the text is at a lower reading level, the font is clearer and the design is more spacious. In addition, there are more frequent in-text questions to break up the text and key term boxes so that new vocabulary is explained on the page on which it first appears with simple, understandable definitions. As with the original Hodder Science series, the books exactly match QCA's exemplar Scheme of Work for Science, introduced in schools from September 2000.
