Students Create Natural Batteries

McKinley science students performed an experiment to make batteries out of food items. Students chose four different food items (fruits and liquids) and which positive and negative electrodes they wanted to use (copper wire or penny for positive and galvanized nail or aluminum foil for negative). They made four different batteries from each of their food items. The goal was to light an LED light and to determine if the batteries were generating electricity by using a volt meter.
