Where can I find science quiz questions with answers?

The science section of the QG Playground quiz library has science quiz questions with answers written for adults, offices and quiz nights rather than exam prep. The general science quiz has 20 multiple choice questions on the science people meet every day: why ice floats, what baking soda is, the pH of water, the heart, brain and skin, India in space from Aryabhata to Chandrayaan-3 and Aditya-L1, and the people behind the telephone, penicillin and the World Wide Web. Each question has four options, the correct answer marked and a short fact where it helps. Read the first 10 free on the pack page. With a free account, add it to your quizzes in one click and host it live on a big screen while players answer on their phones with a room code. Granny, the AI assistant, can add a round on any science topic you choose, such as your own industry.
