Science begins with noticing patterns and asking why things happen. This free science trivia page is for teens ages 14–16. Explore living things, the human body, weather, matter, and everyday forces. The questions range from observations to explanations of processes in the natural world. Consider the process behind a result when a question asks how the world works.
Start 10-question Science quiz
Built for teens ages 14–16, this round asks you to draw on a wider range of knowledge and think through unfamiliar choices. Choose Start Quiz below for a 10-question interactive round selected from a bank of 50 questions for this age and topic. See the correct answer and an explanation after each question. Take the quiz on your own or compare answers with friends, then explore another category.
Niels Bohr's 1913 model depicts electrons orbiting the nucleus in fixed circular paths at specific energy levels, explaining atomic emission spectra.
Avogadro's number is approximately 6.022 x 10^23.
Nuclear fission is the splitting of a heavy atomic nucleus (like uranium) into smaller nuclei, releasing enormous energy — used in nuclear power plants and atomic bombs.
Ohm's law states that Voltage (V) = Current (I) × Resistance (R), a fundamental principle in electrical circuits.
NADPH carries high-energy electrons from the light-dependent reactions to the Calvin cycle; ATP supplies energy rather than reducing power.
Newton’s second law gives F = ma = 2 × 3 = 6 newtons.
A catalyst lowers activation energy, increasing reaction rate without being consumed.
For equal resistors in parallel, equivalent resistance is half either resistance: 3 ohms.
The cerebellum coordinates movement and balance.
Homologous chromosomes pair during prophase I of meiosis; that pairing does not occur in mitosis.
A question about temperature, plants, or energy can lead to a simple experiment or a careful observation. Science trivia works best when you pause to think about what evidence might support an answer. For teens, the explanation is a chance to test the reasoning behind a guess. Follow up on a surprising fact rather than treating the score as the final word.
If an answer is unexpected, ask what you could observe or test to understand it better. A new science question can be the start of a home or classroom investigation. The sample questions above give you a quick look at the subject before you start. You can also take a different category quiz if another interest catches your eye.
Choose Start Quiz to answer 10 multiple-choice questions. The round draws from a bank of 50 questions for this age and topic. Check the explanation after each answer, then move on when you are ready. Your score appears at the end, along with a way to play again.
A later round may include questions you have already seen. If a choice surprised you, use the explanation to talk about why it was right or look for more context. Prefer a different challenge? The age-group page lists the other available subjects, and each one has its own quiz.
