About this quiz
Science underpins everyday life, from the water we boil for tea to the light that lets us read this page. This quiz covers the foundations you probably met in school: chemical symbols, the building blocks of cells, units of measurement and a few facts about the air and the universe around us.
The questions are written to be friendly rather than tricky, but a handful of them reward careful thinking. After each answer you will see a short explanation that puts the fact in context. If you score well, try the harder space and astronomy quiz next.
