A battery can be created by suspending two different metals in an acid. This video illustrates step-by-step how to create a working battery that will actually light up an LED (a little light bulb), using four lemons, wires, copper pennies, and zinc-c...oated nails. Also shows an example of operating a calculator with a lemon battery. From Hila Science. Run time 06:48.

This song parody is written to the melody, "(I've Had) The Time of My Life". In this video, Mr. Edmonds sings about the chemical processes and energy transformations in a simple voltaic cell. Some of the key vocabulary words include the following: vo...ltaic cell, copper, zinc, anode, cathode, oxidized, zinc ions, electrical energy, copper sulfate solution, copper electrode, and copper ions. This is a great resource to help students master this important concept. Middle School and High School students will enjoy this fun, catchy tune. (5:00)
