Is kitab ke baare mein
This is the official General Science textbook for Grade 5 by the Balochistan Textbook Board, Quetta, written under the National Curriculum 2022-23. The book has 10 teaching units plus a glossary and an index. It opens with the human body systems — respiratory and circulatory — then tackles microorganisms and diseases, ecosystems, physical and chemical changes of matter, light and sound, electricity and magnetism, technology in everyday life, the structure of the Earth, soil, and finishes with space and satellites (including NASA and SUPARCO).
Each unit opens with Students' Learning Outcomes, an introduction, and 'Did You Know?' boxes, and builds concepts through labelled diagrams — from the circulatory system to the conduction of sound waves and satellite orbits.

Ustad ka mashwara
Unit 1 (Human Body System) mein stethoscope ya chart se dil ki dhadkan sunwayen — bacha circulatory system kabhi nahi bhoolega. Unit 5 (Light and Sound) torch aur sheeshe se transparent/translucent/opaque ka tajurba karwayen; aawaz ke liye table par thapak kar 'sound travels through solids' dikhayen. Unit 10 (Space and Satellites) bachon ko sab se zyada pasand aata hai — SUPARCO ka zikr khud fakhr se karen, Pakistan ka apna space program hai.
