Is kitab ke baare mein
This is the official General Science textbook for Grade 4 by the Balochistan Textbook Board, Quetta, written under the National Curriculum of Pakistan 2022-23 (author: Dr. Muhammad Hussain Khajjak; editor: Dr. Samiullah). The book has 10 teaching units plus a glossary and an index. It starts with life processes and the structure and function of plants and animals, moves through ecosystems and adaptations, then into physical science — matter, energy, force and simple machines — and finishes with technology in everyday life, Earth's resources, and Earth in the solar system.
Each unit opens with Students' Learning Outcomes and an introduction, then builds concepts through labelled diagrams and activities. Verbatim slogans and slogans like the water-cycle explanation in 'Earth and its Resources' keep the science concrete for young readers.

Ustad ka mashwara
Unit 1 (Life Processes) se shuru karen aur bachon ko school ke bagiche mein le jayen — podon ki growth aur photosynthesis wahan dikhayen, kitab baad mein kholen. Unit 3 mein human digestive system ka labelled diagram bachon se banwayen; daant (molar, premolar, incisors, canine) apne munh mein ungli se pehchanwayen. Unit 9 ka water cycle glass mein ubaltay pani aur thandi plate se practically dikhayen — concept kabhi nahi bhoolenge.
