The Body
Holds Its Line
GCSE Biology Knowledge Mat — Coordination and control (PDF)
How a body detects a change and reverses it — and why every one of these systems works the same way. Nerves and the reflex arc; the brain; hormones, with the menstrual cycle drawn as four hormones across 28 days, contraception and fertility treatment; the eye and its defects; the four values the body will not let go — temperature, glucose with insulin and glucagon, water, and plant hormones — and the negative-feedback loop that runs all of it. Sixteen terms to define, a model answer on blood glucose, and the misconceptions that cost marks.
Everything else this site has for Science: Science teaching resources
One purchase covers the school that buys it. Print it, copy it, hand it round your department. Not for passing to other schools or uploading anywhere.
One landscape A4 page on one topic, led by the figures and photographs rather than the headings. It carries the reflex arc and the brain, the hormones of the menstrual cycle, the eye, thermoregulation, blood glucose with insulin and glucagon, water balance, plant hormones and the negative-feedback loop — then the vocabulary, a worked exam-style answer and the misconceptions that cost marks.
Every photograph on the sheet is a real archival or scientific image, not an illustration and not AI-generated; every diagram is drawn in code for the sheet. Each image was checked against its own licence template rather than a label, and the running foot names every creator, states that the images have been cropped and adjusted for print, and links the licence — so the sheet can be photocopied for a class and stay compliant. Every claim is sourced to the DfE subject content, and nothing is reproduced from a past paper, a textbook or a specification.
Sold by subject: all four biology sheets for one price. A knowledge organiser stores a unit and is revised from afterwards; this is meant to be on the table while the work is happening.
- Written to The DfE GCSE subject content for biology (DFE-00351-2014). Every photograph is a sourced archival or scientific image, licensed for reuse and credited on the sheet; every diagram is drawn in code for the sheet
- Intended for biology teachers — on the desk during the lesson, not a student revision guide
