In Dragon Academy, Health & Body Science is taught by Pulse. Every question a kid answers correctly trains Pulse to grow and evolve. Here are real questions from the game — tap an answer to check it.
On this page kids practice real body science: how muscles, the heart, and lungs work together during exercise, what bones do, how much sleep school-age kids need (9–12 hours), what water and warm-ups actually do, and food as fuel — carbohydrates for quick energy, protein for muscle repair. Every question comes with a short explanation and a fun fact worth repeating at dinner.
The four difficulty tiers climb steadily. Easy questions — which part of the body pumps blood to working muscles? — suit 7- and 8-year-olds. Medium explains why muscles feel sore a day or two after a workout (hint: not lactic acid) for ages 9–10; hard covers VO2 max, muscle fiber types, and how REM sleep locks in skills; expert reaches real exercise science — the central governor theory of fatigue, autophagy, and hormesis — a genuine stretch for 12- and 13-year-olds and for many adults, too.
In Dragon Academy, every correct answer trains Pulse, the game's health dragon, who grows and evolves as your child's knowledge does. The five sample questions on this page are free to try — tap an answer to check it and read the explanation behind it.
The full game has 100 Health & Body Science questions across difficulty tiers — plus dragons to raise, hybrids to breed and a story library to read. Free, no ads.
