Volume 5, 'The Battle of Electricity,' covers key foundational concepts related to electricity, including electrons and electric current, electromagnets, batteries, and electric circuits. This volume comes with a fun and fascinating experiment kit that lets kids light up an LED using only fruits or vegetables—no battery required! The kit includes alligator clip wires, zinc and copper plates, an LED, and a photo guide created by the editorial team based on their own hands-on testing. Through this experiment, children can easily and playfully learn the principles and process behind how electric current is generated.
