This page is built for students looking for class 9 science practice test, chapter practice, and quick school exam revision.

Why this practice page is useful

Use this Class 9 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 9 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. Newton's First Law: An object remains at rest or in uniform motion unless acted on by an external force (law of inertia).
  2. Atom and molecule: Atom – smallest particle of an element. Molecule – group of two or more atoms chemically bonded.
  3. Function of cell membrane: Controls movement of substances in and out of the cell; gives shape and protection.
  4. Speed vs velocity: Speed – distance/time (scalar). Velocity – displacement/time (vector, has direction).
  5. Tissue and two plant tissues: Group of similar cells doing a function. Examples: meristematic and permanent (parenchyma).
  6. Newton's three laws: 1) Inertia. 2) F = ma. 3) Action = -reaction.
  7. Velocity and SI unit: Displacement per unit time. SI unit: m/s.
  8. Mass vs weight: Mass – amount of matter (kg, constant). Weight – force of gravity on mass (N, varies with g).
  9. Three states of matter: Solid (iron), liquid (water), gas (oxygen).
  10. Atom and first atomic theory: Atom – smallest unit of matter. John Dalton proposed the first atomic theory.
  11. Tissue and two plant tissues (repeat): Same as Q5: meristematic and permanent (parenchyma, collenchyma, sclerenchyma).
  12. Law of conservation of mass: Mass can neither be created nor destroyed in a chemical reaction.
  13. Speed vs velocity (repeat): Speed – scalar (only magnitude). Velocity – vector (magnitude + direction).
  14. Two viral diseases: Common cold and influenza (also dengue, polio, COVID-19).
  15. Archimedes' principle: An object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced.
