# Science — NCERT Class 7 — CBSE (NCERT textbooks) — Shishya school context > Subject page: https://shishya.in/schooling/cbse/class-7/science · class: https://shishya.in/schooling/cbse/class-7 (context: https://shishya.in/schooling/cbse/class-7/context.md) · data as of 2026-10-11 (IST). Free to cite; link back to the subject page. > Honesty: Shishya never reproduces, summarises or translates textbook text — read a chapter at its official link. Practice questions are Shishya's own, written by AI and answer-checked before they are shown; they are not NCERT exercises, not board questions and not previous-year questions. A chapter marked "not ready yet" has no Shishya notes or practice, and its Shishya page is not linked here. > Children: Class 1-7 school pages have no chat tutor, offer no sign-in and ask no child to create an account. On Class 8-12 pages a student may sign in to save practice to an account — for students 13 and above; no school page asks anyone their age or role — and anyone can read a chapter, take its practice where the chapter has one and ask the AI tutor about it without signing in; the tutor says it is an AI and answers study questions only, with a daily message limit. The 5-question practice on the chapter pages that have it needs no account, and no result is saved to any account or profile from it: Shishya records only an anonymous usage event (which chapter was practised and the score) — on Class 8-12 pages with the same cookie-based analytics every page view sends, on Class 1-7 pages with no cookie, account or other visitor identifier. A signed-in student's own practice set is saved to that account. ## Science - Book: Curiosity — https://ncert.nic.in/textbook.php?gecu1=0-12 (NCERT also lists 22 other-language editions) - Chapters (12; 12 with Shishya notes, 12 with answer-checked practice of 5+ questions): - Chapter 1 — The Ever-Evolving World of Science — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/the-ever-evolving-world-of-science · official PDF: https://ncert.nic.in/textbook/pdf/gecu101.pdf - Chapter 2 — Exploring Substances: Acidic, Basic, and Neutral — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/exploring-substances-acidic-basic-and-neutral · official PDF: https://ncert.nic.in/textbook/pdf/gecu102.pdf - Chapter 3 — Electricity: Circuits and their Components — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/electricity-circuits-and-their-components · official PDF: https://ncert.nic.in/textbook/pdf/gecu103.pdf - Chapter 4 — The World of Metals and Non-metals — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/the-world-of-metals-and-non-metals · official PDF: https://ncert.nic.in/textbook/pdf/gecu104.pdf - Chapter 5 — Changes Around Us: Physical and Chemical — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/changes-around-us-physical-and-chemical · official PDF: https://ncert.nic.in/textbook/pdf/gecu105.pdf - Chapter 6 — Adolescence: A Stage of Growth and Change — Shishya notes + 48 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/adolescence-a-stage-of-growth-and-change · official PDF: https://ncert.nic.in/textbook/pdf/gecu106.pdf - Chapter 7 — Heat Transfer in Nature — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/heat-transfer-in-nature · official PDF: https://ncert.nic.in/textbook/pdf/gecu107.pdf - Chapter 8 — Measurement of Time and Motion — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/measurement-of-time-and-motion · official PDF: https://ncert.nic.in/textbook/pdf/gecu108.pdf - Chapter 9 — Life Processes in Animals — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/life-processes-in-animals · official PDF: https://ncert.nic.in/textbook/pdf/gecu109.pdf - Chapter 10 — Life Processes in Plants — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/life-processes-in-plants · official PDF: https://ncert.nic.in/textbook/pdf/gecu110.pdf - Chapter 11 — Light: Shadows and Reflections — Shishya notes + 38 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/light-shadows-and-reflections · official PDF: https://ncert.nic.in/textbook/pdf/gecu111.pdf - Chapter 12 — Earth, Moon, and the Sun — Shishya notes + 47 answer-checked practice questions: https://shishya.in/schooling/cbse/class-7/science/earth-moon-and-the-sun · official PDF: https://ncert.nic.in/textbook/pdf/gecu112.pdf - Shishya content last updated: 2026-09-26 ## Other subjects in this class - Hindi: https://shishya.in/schooling/cbse/class-7/hindi - English: https://shishya.in/schooling/cbse/class-7/english - Mathematics: https://shishya.in/schooling/cbse/class-7/mathematics - Social Science: https://shishya.in/schooling/cbse/class-7/social-science - Sanskrit: https://shishya.in/schooling/cbse/class-7/sanskrit - Arts: https://shishya.in/schooling/cbse/class-7/arts - Physical Education and Well Being: https://shishya.in/schooling/cbse/class-7/physical-education-and-well-being - Vocational Education: https://shishya.in/schooling/cbse/class-7/vocational-education - Urdu: https://shishya.in/schooling/cbse/class-7/urdu
