INVESTIGATING THE DESIGN AND OUTPUT OF
WET CELL BATTERIES
Kit #205S — Developed by SEPUP

This kit introduces students to the concept of energy conversion through the study of a
simple electrochemical cell connected to an electric motor . Students design and conduct an
experiment that uses the unique Lab-Aids Wet Cell Chamber to determine which combination
®
of different metals works best to convert the potential chemical energy into electric energy .
Their results allow them to rank the metals tested in order of reactivity . They also investigate
how the distance between the metals, the direction of current flow, and the amount of metal
surface area impacts the electrical output of the wet cell . .

Accommodates 6 groups of four students.
