A daily science quiz you can point at in the world around you

Five questions a day, with science questions on physics, biology and chemistry you meet in everyday life. Every answer comes with a plain explanation and a takeaway worth keeping.

What the science questions cover

The Science category sticks to things you can point at: mechanisms and causes in the world around you, rather than equations you would only see in a classroom.

  • Physics in the everyday

    Gravity, heat, light and pressure — the forces at work in your kitchen, your phone and your commute.

  • Biology of you

    Sleep, food, immunity and the body's odd habits — practical questions rather than textbook diagrams.

  • Chemistry you can point at

    Why soap works, why food browns, why batteries die: reactions you witness without noticing.

  • Earth and space

    Weather, seasons, the moon and the scale of things — the parts of science most people meet through the sky.

Why one science question a day works

Science is mostly a set of explanations you keep forgetting you know. Answering one question a day — and reading why the answer is true — rehearses those explanations at the moment a textbook would have lost your attention.

Each question closes with a takeaway, so even a wrong answer leaves you with something usable. Your streak, accuracy and strongest categories build up as you play — as a guest on one device, or across all of them with a free account.

Science is one of seven subjects in the daily round — see the full general knowledge quiz for what else a day covers.

Science quiz questions

Is this science quiz free?
Yes. The daily round is free to play, with no ads interrupting a question and no account required.
Will all five questions be about science?
No — the daily round mixes 5 questions across Money, Technology, Health, Travel, History, Science and Everyday Life. If you want a pure science quiz, the Science category is usually represented once or twice each day, and every question still comes with a full explanation.
Do I get the answers explained?
Yes. After each question you see whether you were right, what the correct answer is, why it is true, and one takeaway to remember — for science questions, usually a mechanism you can picture rather than a formula.
What if my science is rusty?
That is fine. The daily five span difficulty levels, and the explanation teaches what the question tested. Starting from a wrong answer is a completely normal way to use TipIQ.
When is a good time to play?
The round takes about five minutes, so it fits a coffee break, the commute or a wait. One science question a day adds up faster than most people expect — that is the whole idea.
