Free science quiz for kids

How our world works, in tap-sized questions. Original ClassVani science quiz — not official exam papers.

Tap-sized science questions introduce how the natural world works — plants, forces, and everyday physics for Class 4–10 bands. Encourages curiosity rather than long textbook chapters. Questions stay multiple-choice so children practise exam-style thinking without a timer pressure.

Turn up your device volume when a game speaks letters, words, or instructions. Pick the answer that best matches the science fact or diagram described. Talk through wrong taps with your child if they are unsure. Tap your answer; ClassVani shows right or wrong immediately, then shuffles items on the next round so repeats stay fresh.
