Here are the present UK KS3 science Units arranged in an order that represents their distance from a young learner’s world-experience. The units are broadly grouped into Biology (green), chemistry (blue) and physics (orange) related topics. Notice how some conceptually challenging topics (like the particle description of matter), are introduced early in the standard scheme timetable. I have included an editable version in MS Word format should you wish to suggest changes.
Perhaps it is time to revise the scheme to improve its relevance to living in the modern world. I suggest three broad themes of Health, Technology and Environment, encompassing topics that will be used in a normal working adult life. There is again an editable version in MS Word format. Parts of the current schem can be introduced as appropriate.
