Here are a few explorations of electric current.
Hand battery snack, measure the current created when your hands touch two different metal plates.
Salt water battery, use salt water with copper and aluminum elctrodes to create a battery.
Aluminum Air Battery, aluminum foil wrapped around salt water soaked activated carbon creates a high current battery.
Battery Dissection, take apart a battery to see what's inside.
Quiet Lightning exhibit, This exhibit was built at the Exploratorium by artist in residence Bill Parker.
Neon Tubes exploration, these tubes run on high voltages but very low currents.
Making Battery Holders, there are several easy ways to hold batteries and connect wires to them.
Ammeter, build your own sensitive ammeter.
Meters, Current , use several meters to measure the current at many different places in a simple electrical circuit.
Battery Bulb meter, measure the voltage across and the current through a bulb in a flashlight circuit.
Electric Current Model, Use magnets to model the behavior of electric current.
Domino Model of a Nerve, Use a line of dominos to model the behavior of a nerve.
Voltage Measure the voltage across one and two batteries, explore the meaning of voltage.
