Properties of matter, physical and chemical changes, particles and conservation of mass.

Students act out the particles. Huddle and vibrate for a solid, slide and sway for a liquid, spread out and zoom for a gas.

A single-player chemistry game for grades 6–8. Race through the lab with atoms and molecules, states of matter, density calculations, chemical reactions, conservation of mass, and exothermic and endothermic reactions, then finish with a skills report for five middle school NGSS matter standards.

A team review game for every NGSS middle school physical science standard. Teams claim tiles on a map by answering questions, and can steal each other's tiles. Play a full review or pick the standards you want. The results show % correct for each standard.
