Pickle Juice
Students generate experimental questions regarding conductors of electricity, plug cord into pickle, and measure and graph voltage drop across electrodes. Students then compare to variety of other conductors of their choosing.
Curated OER
Scouting for Circuits
Fifth graders investigate electricity and how it used in a circuit to be useful energy. They also use this investigation in order to understand how energy can change forms and still be considered useful if put into the right form.
