Science Trivia Questions and Answers in Five Rounds: how it works
Which metal makes stainless steel stainless, and which point did Celsius mark as 0 degrees? These 150 science trivia questions and answers come in five rounds of 30. Tap a choice, press Check answer, and read the reason.
Pick a subject for the round
Topic lists five subjects: Physics, Chemistry, Life science, Earth and space and Inventions and discoveries. Choose one and all 30 questions come from it. For a quiz night, read each question and its four choices aloud, let teams write a letter, then press Check answer for the reason. Scores stay on paper.
Warm up on the easy ten
Every subject holds ten easy questions, twelve medium and eight hard. The levels are our estimate. Easy asks for the everyday name of sodium bicarbonate; hard asks where Ytterby is, the village that gave four elements their names. Print question sheet sets out the next 20 with lettered choices, and Print answer key adds the reasons.
Tips
- Pair Physics with Inventions and discoveries for a night on electricity: the transformer, Ørsted's compass needle and the Leyden jar all turn up.
- The reasons are worth reading out. Pavlov's dogs began to salivate when the technician who fed them walked in, before any food arrived.
- Send a class the same quiz with Share this set: the link keeps the questions and their order.
Questions and answers
Have the answers been checked?
Yes. On September 19, 2026 we read each answer, and each added fact in its explanation, in the Wikipedia article linked under the question. Where the article was vague, the detail came out or the question went.
Is this pack right for kids?
It is written for teens and adults. The easy level suits a mixed family table, but hard asks for Cherenkov radiation and the Holocene. Younger players have their own science pack on this site, and none of its questions repeat here.
Why is there no human body round?
The life science round stays with animals, plants, fungi and the naturalists who studied them, and leaves the human body out. It shares no question with the biology pack, so the two can run on the same night.
What does a hard science question look like?
Hard asks what the Italian name neutrino means, or which island held woolly mammoths until about 4,000 years ago. The answers are little neutral one and Wrangel Island. Each round has eight questions at that level.
