Explore Science Innovative Detector Challenge – STEM

Explore the relationship between electricity and magnetism with this metal detector challenge set from Explore Science. Using the components, users can build a handheld metal detector with adjustable sensitivity, a mini security check station, or an aim and shoot challenge designed to demonstrate how parabolic motion affects detection. In addition to the detector challenges, junior scientists can test their hand-eye coordination and learn basic circuitry principles by building a simple maze game using a bendable wire, a wand and an alarm bell.
