How the universe, the planet and everything living on it actually work.
Science is the largest section on QuizKite, and the one where explanations matter most. Knowing that a proton is positively charged is trivia. Knowing why that single fact determines the entire periodic table is understanding, and that is what these quizzes are built to give you.
Inside you'll find physics, chemistry and biology, along with the parts of science people actually meet day to day: the weather, the oceans, animals and birds, plants, the human body, the ground under your feet and the sky above it. The difficulty ranges from questions a curious ten-year-old could answer to a few that will catch out people who studied the subject.
Every answer comes with a short explanation of the mechanism behind it. That is deliberate. The mechanism is the part you remember a week later.
The universe, the atom, and every living thing in between.
Records, behaviour and the logic of how animals live.
