You can also create a circuit with RGB LED lights, and let the LEDs emit different colors of light by changing different experimental materials .
Advantages: Through complete the fruit battery science experiment project with Student, it can create student's imagination, improve hands-on ability, increase scientific knowledge, and cultivate scientific invention hobbies
