VAN DE GRAFF Generator By Gary Zhong

What is an ATOM?

What is an atom made of? 1. Protons: positive charge 2. Electrons: negative charge 3. Neutrons: no charge

Analogy: Planets orbiting the sun

Where are the basketballs and tennis balls located?

“Like charges repel, opposite charges attract”

Glass rod and silk cloth demo

Hair and comb demo Combing your hair moves electrons from your hair to the comb The comb will now have an electric static charge

What is a Van de Graff Generator? The basic fundamental principle behind this apparatus is separating opposite charges at both ends of the rubber belt

Key Materials Motor Belt Metal sphere Rollers and Brushes

How it works!

Zoom in on our hair

Hair raising demo

Electric spark demo

Has anyone felt a shock on dry winter days? THE SAME PRINCIPLE APPLIES
