Carolina STEM Challenge®: Battery Dilemma Kit

(in stock)


Allow your students to assume the role of electrical engineers, designing batteries using a potato and pairs of dissimilar metals. Students compare various metals as they attempt to produce the highest-voltage, and eventually the best, battery. Student groups then compete to design ways to boost and to alter the voltage output of their batteries. This kit is designed for 10 lab stations with students working cooperatively in groups of 3.

FREE 1-year access to digital resources that support NGSS instruction included.
