This syllabus is organized into 17 sections (or "maps") which focus on these topic areas: the earth in the universe; variety and adaptation; reproduction; growth; food and feeding; sensitivity; microscopic living things; movement, forces, and structures; heat; light and color; sound; magnets and magnetism; electricity; water and other liquids; air and other gases; materials; and rocks and minerals. Each map consists of two parts and a sample scheme of work. The first part describes core investigation techniques in detail. Examples are given of the kind of question or idea which can start an investigation, the kind of experimental planning to be done, the kind of causal explanations students might give, and problems which might be tackled. A complete list of core techniques is given for the collecting of evidence, recording, calculating, and looking for patterns. The second part describes the development of scientific ideas in three categories: core ideas (which can be grasped by 13-year-olds); supplementary ideas; and extension (abstract) ideas. The sample scheme of work lists (with references) a variety of activities teachers can use. Information on using the maps in program planning, principles underlying a description of core science, and core science within the whole curriculum is included. (JN)
