Science Challenge Quiz
A broad sweep through physics, chemistry and biology — the kind of general science knowledge that turns up in pub quizzes, exams and arguments with confident friends.
Play nowTen questions across every branch of science.
Ten questions, no timer, no penalty for guessing. Use the number keys 1-4 if you are in a hurry.
The science facts that keep coming back
A handful of numbers and definitions underpin most of what general science quizzes ask.
Physics, chemistry and biology share a small set of anchors that appear again and again: the speed of light, absolute zero, the composition of the atmosphere, the structure of the cell and the meaning of pH. They recur because they are the reference points everything else is measured against. Learn why each value matters rather than memorising it, and questions that look unrelated start pointing at the same handful of ideas.
Scoring: one point per correct answer. 0-3 makes you a Beginner, 4-7 an Explorer and 8-10 a Master. Your best result is kept in this browser, so you can come back and try to beat it.
