The Division of Specialized Information Services (SIS) of the National Library of Medicine (NLM) has launched TOXinvaders, an environmental health and toxicology game for the iPhone and iPad. It is available from the Apple Store. TOXinvaders supports middle school science concepts pertaining to chemistry, the environment, and health. It can serve as an engaging classroom or homework activity for middle and high school students, as well as an entertaining learning activity for gaming aficionados of all ages. In the classroom environment, TOXinvaders works best as a supplement to NLM’s Tox Town, Environmental Health Student Portal, TOXMAP, and ChemIDplus Web sites.
The game consists of four fast-paced levels, in which a launcher is used to annihilate toxic chemicals falling from the sky and earn protective shield points by capturing “good chemicals.” To move on to the next level, players must take a brief quiz about the chemicals. These dynamically generated tests provide an excellent opportunity to learn more about environmental health and toxicology from the game’s chemical information sheet and from NLM Web sites. Quiz questions and answers can also serve as a starting point for classroom discussions, as well as for Tox Town, TOXMAP, and Environmental Health Student Portal activities and experiments.
