This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.
