Six half-termly units across one academic year, two each of biology, chemistry and physics. Each discipline starts where it actually starts — biology at the cell, chemistry at the particle model, physics at forces — because nothing else in the key stage works if those three are shaky.

The six units:

Ten sections per unit, in the same order every time. Lessons are one row each rather than a page each — enough to teach from, and little enough that a department can actually keep it up. Every unit maps to the statutory programme of study for key stage 3 science (DfE, 2013).

For heads of science, subject leaders, technicians and every teacher who has to deliver it. 40 pages, A4 PDF.

If you use it, a review would be very welcome
