Do you know how batteries work? Batteries store electrical energy in the form of chemical energy, which means that electrochemical reactions inside the batteries create electricity. It may sound complicated but it is simpler than you think! In this activity you will create a basic homemade battery with just construction paper, vinegar, salt and a handful of pennies and washers—and prove it works by lighting an LED!
20 metal washers (galvanized; the size of a penny)
20 pennies (preferably shiny)
Small white or red LED
Work area that can tolerate vinegar spills
Aluminum foil (optional)
