With 100 stem experiments in one box, owi is redefining value! 100 in 1 Stem lab will teach children how the world around them connects. Young scholars, ages eight and up, will learn about basic circuit connections as they construct four initial units (maze challenge, flying disc, turbo Air, and alarm system). maze challenge allows children to build a carnival classic hand eye coordination game where a metal loop is maneuvered around a metal wire without making contact; difficulty of the wire can be adjusted. Flying disc allows children to launch a disc spinning into the air.
