Every question below has a third column, “Why it’s worth knowing”. It holds the reason behind the answer, or a connected fact. Class 4 kids are old enough to ask “but why?”, and an answer with a reason attached is much easier to remember. For a younger brother or sister, these GK questions for Class 2 follow a kid through an ordinary day instead.

Three answers quiz books often get wrong

1. The largest desert

Many quiz books say the Sahara, but a desert is defined by how little rain or snow falls there, not by heat. On that measure, Antarctica is the largest desert. The Sahara is the largest hot one. Checking what a word actually means before trusting an answer is how scientists work, and it’s a habit Bambinos’ science classes online try to build through experiments.

2. Who invented the computer?

Charles Babbage designed an early mechanical computer, which is why he is called its father. But no single person invented the computers we use today. They grew out of the work of many scientists across more than a century.

3. Penicillin

Fleming discovered penicillin. He noticed that a mould on one of his laboratory dishes was killing bacteria. He didn’t design or build it, so “invented” is the wrong word.

Knowing an answer is one thing. Explaining it clearly to someone else is another. Bambinos’ live classes give kids regular practice at the second, in small groups where they’re encouraged to ask “why?” If that sounds like your kid, try a Bambinos class free of charge.
