Is kitab ke baare mein
This is the English-medium 'PNB Biology (EM) 2023-24' practical notebook of the Punjab Curriculum and Textbook Board for class 9 — not the theory textbook, but the official practical manual. It walks students through 30+ syllabus experiments: from studying bacteria, Amoeba and Paramecium under the microscope, dissecting a frog's organ systems, and observing mitosis in root-tip squashes, to testing enzyme action, photosynthesis in Hydrilla, food tests for sugar/starch/fat/protein, and transpiration and transport experiments in plants.
What makes the PNB edition distinct is its laboratory-first structure: every chapter is built around numbered experiments with page references, plus general guidelines, safety procedures, biology-drawing rules and microscope instructions up front, and a completion certificate at the start for the student's session. The Urdu-medium twin ('PNB Biology (UM) 2023-24') carries the same practical syllabus for Urdu-medium students.

Ustad ka mashwara
Is practical copy ka asli faida tab hai jab har experiment ka diagram student khud banaye — ready-made charts se copy karwana practical ka maqsad khatam kar deta hai.
