In Dragon Academy, Chemistry is taught by Reagent. Every question a kid answers correctly trains Reagent to grow and evolve. Here are real questions from the game — tap an answer to check it.
On this page kids practice real chemistry: the three states of matter, the formula for water, the gases we breathe in and out, element symbols from gold (Au) to iron (Fe), everyday acids and bases like lemon juice and baking soda, plus atoms, molecules, and what happens when iron rusts. Every question comes with a short explanation and a fun fact worth repeating at dinner.
The four difficulty tiers climb steadily. Easy questions — what is the chemical formula for water? — suit 7- and 8-year-olds with no prior knowledge. Medium introduces the periodic table's groups, ionic versus covalent bonds, and the pH scale for ages 9–10; hard brings molar mass, the ideal gas law, and electron configurations; expert reaches organic and analytical chemistry: functional groups, buffers, racemic mixtures, equilibrium constants, and mass spectrometry — a genuine stretch for 12- and 13-year-olds and for many adults, too.
In Dragon Academy, every correct answer trains Reagent, the game's chemistry 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 Chemistry questions across difficulty tiers — plus dragons to raise, hybrids to breed and a story library to read. Free, no ads.
