Games

Grade 9-12 Chemistry Tools & Labs

Atom Ninja

Build atoms in the lab and play Atom Ninja — slower movement, longer time, and correct targets appear more often.

Chem Catch

Read the ionic question and shoot the fish with the correct formula — a fast ionic-formula practice game.

Lab & Hazard Match

Memory game: match bilingual lab apparatus names to pictures and OSHC chemical hazard labels.

Flame Test Fireworks

Design metal-ion burst patterns, launch them over night-sky scenes, and download your flame-test firework display.
