This page is built for students looking for class 7 science practice test, chapter practice, and quick school exam revision.

Why this practice page is useful

Use this Class 7 science practice test page to start with a ready-made sample instead of typing everything from scratch.

The generated paper mirrors the tone of a Class 7 science exam and works well for school revision, homework support, and quick mock tests.

You can replace the starter questions with your own textbook or worksheet content for more targeted science practice.

Answer key & quick explanations

Short answers for the sample questions above. Use this to self-check before generating a fresh AI-built mock test.

  1. Nutrition in plants: Process by which plants take in nutrients (mainly through photosynthesis using COâ‚‚, water, sunlight).
  2. Acids vs bases: Acids – sour, turn blue litmus red (lemon). Bases – bitter, turn red litmus blue (soap).
  3. Heat and transfer: Heat is a form of energy; transferred by conduction, convection and radiation.
  4. Physical vs chemical changes: Physical – no new substance, reversible (melting). Chemical – new substance, often irreversible (rusting).
  5. Reproduction in living organisms: Process by which living things produce new individuals of their kind.
  6. Photosynthesis word equation: Carbon dioxide + Water → (sunlight, chlorophyll) Glucose + Oxygen.
  7. Heat conductors vs insulators: Conductors transfer heat well (metals); insulators do not (wood, plastic).
  8. Why farmers add manure: To replace nutrients lost from the soil and improve fertility.
  9. Respiration: Breakdown of glucose with Oâ‚‚ to release energy; takes place in mitochondria of cells.
  10. Two organs of respiratory system: Lungs and trachea (also bronchi, diaphragm, nose).
  11. Weather vs climate: Weather – day-to-day atmospheric condition. Climate – long-term pattern over many years.
  12. Why iron nail rusts: Iron reacts with oxygen and moisture to form iron oxide (rust).
  13. Two adaptations of desert plant: Thick waxy stem to store water; spines instead of leaves to reduce water loss.
  14. Balanced diet: A diet with the right amount of all nutrients – carbs, proteins, fats, vitamins, minerals, water.
  15. Physical vs chemical changes: Same as Q4 – physical: reversible, no new substance; chemical: new substance formed.
