Looking for a free printable quiz with a science and nature theme, ideal for a pub quiz night, classroom science lesson, or office trivia break? This quiz comes ready to print in two lengths: a quick 25-question version for a shorter session, or the full 40-question version split across five rounds covering Earth and the environment, the human body and health, animals and wildlife, space and physics, and chemistry and inventions. Each round mixes easy, medium, and trickier questions, so it works for a general audience rather than just the science buffs in the room.

Printing works the same way as our other printable quizzes. Open the page, choose your length, and you’ll get a clean question sheet to hand out, plus a separate answer key for the host so marking stays quick and accurate, with no risk of players spotting the answers mid round. It’s free to print and reuse as often as you like, whether that’s a recurring pub quiz, a science class warm-up, or a few minutes of trivia at the start of a team meeting.
