Biology, physics, chemistry, scientists and India's science missions: science quizzes for students and the curious, with every answer explained.

What is a science quiz?

A science quiz tests how well you understand the ideas behind everyday things: how the body works, why metals rust, how plants make food and how rockets reach orbit. For a general round, try the Biology Quiz, the Planets Quiz, the Famous Scientists Quiz on the people behind great discoveries, or the Famous Mathematicians Quiz. For exam preparation, the science topic quizzes follow the general science syllabus of SSC, railway and state exams: physics in everyday life, basic chemistry, cell and plant biology, the human body, diseases and nutrition, biotechnology, computer basics, ISRO's space missions, India's nuclear energy programme and defence technology. Each topic quiz comes with study notes and graded practice sets, from easy to hard. Every question, in every quiz, shows the right answer and a short explanation as soon as you pick. All quizzes are free, work on a phone and need no sign-up.
