The ElectroscopeBuild an electrophorus, explain how it works and charge with it a homemade electroscope. R R R R R R R R R Build an electroscope and demonstrate the existence of two kinds of charges (positive and negative). R R R R Build an electroscope and classify materials according to electrical conductivity (insulators and conductors). R R R Build an electroscope and compare electron affinities of different materials (triboelectric series). R R R R R Test what distance different electroscopes can sense an electrical charge and what factors affect it. R R Build an electronic electroscope (charge detector) and compare its sensibility to a conventional one. R R Will the more charge gained through more comb strokes, the further away it will be detected and will a longer antenna increase the detector's sensitivity? R
Different Electrostatic MachinesThe Effect of the Shape of an Electrostatic Comb on the Charge Production of a Van de Graaff Generator R Build a Simple Electrostatic Motor R R R R A Revolution in Electrostatic Motors R Build a Wimshurst Influence Machine and improve on the design of the machine through experimentation. R R Explore the mechanism of electrostatic induction by repeating Faraday’s "Ice Pail" experiment and explain its applications (Faraday Cage). R R R R R R R R Build and demonstrate a Van de Graaf generator. R R R R R R R R Build a Kelvin Water Dropper. R R R R R R R Build a Dirod Electrostatic Generators R R Static Electricity MiscellanyWhat Materials Conduct Static Electricity Best? R How Do Different Materials React to Static Electricity? R Determine what effects have different weather conditions on the magnitude of a static charge produced by rubbing a comb with various types of cloth. R Test if the number of rubs of wool on a balloon increases or decreases how long the static charge will last. R Can static electricity make a neon light glow? R R R R Determine what was the best method to remove static electricity from different common materials in various environments. R Will a spark arc from an electrical source to the north pole of a magnet. R Build and experiment a cloud charge monitor.
