LED Battery Exploration Pack Set

Grades 7-12.

Explore how light is used in technology products using STEAM methodology with this hands-on classroom kit that has students construct their own pile battery that will light a 3.5V (20mA) LED lamp using zinc and nickel planchets. Students view a guide image of a quarter battery with an illuminated LED light, then use this image as a design prototype while building their pile battery. After the battery is assembled, students will evaluate its power performance and energy density characteristics. Students will then investigate the difference between an acid electrolyte and an alkaline electrolyte in the Ni-Zn battery system. They are asked to design an alkaline Ni-Zn pile battery and compare its energy performance characteristics to that of the previously constructed acid pile battery. From this comparison, students determine which electrolyte type (acid or alkaline) provides for a higher energy density (Wh/Kg) at the same output voltage.
