Electroplating for Corrosion Protection: Redox in Action
Students define what a redox reaction is. In this chemistry activity, students electroplate some wires in the lab. They research the application of electroplating in the real world.
Exploratorium
Salty Pits
Yuck, does my deodorant kill that? To test whether deodorant is anti-bacterial, class members use petri dishes to grow control bacteria and bacteria from sweat, and then compare them to see if deodorant effects the growth.
