General Science, class 8

Sindh and KP again publish the same twelve-chapter book in the same order — human organ system, heredity, biotechnology, pollutants, chemical reactions, acids and alkalis, force and pressure, measurement, sources and effects of heat energy, lenses, electricity in action, exploring space — both National Curriculum 2006, and no board difference should be claimed. This is also the KP cell the 2022 rollout did not touch: KP modernised class-8 Urdu, Islamiat, History, Geography, Mathematics and Computer Science, but left English and General Science on the 2006 curriculum, so this book sits beside genuinely rebuilt 2022 volumes in the same schoolbag. Punjab overlaps more here than at any other science grade, retaining Biotechnology, Chemical Reactions, Acids/Alkalis/Salts and Force and Pressure, but reorders the front of the book to lead with Ecology, adds a Periodic Table chapter, and again carries Technology in Everyday Life. The scores are almost flat and the cell is thin for social analysis. KP's is the most content-neutral book in the entire corpus, with a religious-term density of 0.00 across 169 pages and no lens evidence entries at all — hence A1 1, the corpus floor. Punjab is also A1 1 on a bismillah and nothing else. Sindh scores 2 not on body text but on its preface, which states the aim that "our new generation must be well conversant with the Islamic ideology" (PAGE 4). All three score A7 5 by absence; Punjab's apparent ratio of 0.211 is an OCR artefact and the true figure is nearer 0.05. Climate change is well covered by all three at this grade. What separates them is only currency: none of the Sindh or KP material mentions COVID-19. At class 8 the three boards teach almost the same science, and the only thing that distinguishes their books is which decade they were written in.
