The after-school science club at Galtier Math, Science, and Technology Elementary Magnet School in St. Paul, Minnesota, learned some valuable lessons when they took newfound knowledge about pollution into their homes. After learning about the effects of various contaminants on health and what informed citizens can do about it, students tested their tap water and soil. As a result, both students and their parents changed behaviors. The experience proved valuable for the educators too, reminding them of the power of integrating science with real-world issues and how effective they can be in guiding children to make more informed decisions about their world.
