Relate voltage, resistance and current in an ideal circuit. Model assumptions remain visible.
Revisit selected plant nutrition, ventilation, gas exchange and pumping/transport relationships through bounded original investigations.
What must be connected for the bulb to light?
Connect the components, close the switch and investigate a continuous electrical path.
How does air reach the living cells inside a leaf?
Turn a leaf, inspect its surface and open its layers to connect structure with gas exchange.
Why can more light stop increasing this model's photosynthesis rate?
Change relative light and carbon dioxide availability, then explain a plateau in a disclosed rate model.
How does changing diaphragm movement affect fresh-air entry, and when does chest motion fail to tell the full story?
Control a chest model, compare fair trials and trace two gases before explaining where energy is released.
What does pumping change, and why is blood not used up when it delivers oxygen?
Construct a loop, follow the same blood courier and compare pumping with no pumping while oxygen cargo is exchanged.
Concepts connect across chapters, classes and subjects.

Unit text pp. 4–6 and practical list inspected. Periodic Classification, Evolution, Motor/Induction/Generator explicitly labelled formative-only. Final teacher note says Heredity and Evolution and Electric Effects of Electric Current are not year-end assessed, while unit text includes Heredity and current. This internal inconsistency needs school/CBSE clarification; platform makes no exam inclusion promise. Optical group headings are Bodhi groupings of syllabus sections, not verified NCERT chapter titles. Inspected scope: curriculum.
Actual 2026–27 chapter body, catalogue and pulmonary-vessel diagram inspected. Supports bounded X revision and clearly labelled optional named chamber/vessel extension. No full Life Processes coverage; X detail is not used to establish VII placement. SHA-256 685ec7228afeb79d7bc9b989648e381e5eb4b5a6d290d6a13374489c9284054f.
2026–27 Class X curriculum inspected; current, potential difference, resistance and Ohm’s law are listed. Some further topics have formative-only assessment notes.
