50 GK Questions for Class 7

Class 7 students meet GK mostly in multiple-choice form, in school quizzes, Olympiads and entrance tests. So every question here has four options. The answer and a one-line reason follow straight after, which helps students work out why the wrong options are wrong.

Questions about recent events are dated. They were checked in November 2026.

Science

Using these for test practice

When a student gets a question wrong, ask them to explain why each wrong option is wrong. On question 2, for instance: “The joule is for energy, the watt is for power...” Working through options like this is what improves scores in multiple-choice tests, because it trains students to rule answers out instead of guessing.

Bambinos’ live online classes for kids build the same habit of reasoning out loud, in small groups with a teacher, and the first trial class is free.
