Curated OER
Electric Charge and Static Electricity
Begin with the classic static electricity demonstrations: the behavior of charged balloons and metal leaves of an electroscope. Then move on to test the electrical conductivity of various materials. Give physics pupils a charge with...

Electroscope
Students examine what an electroscope is and who invented it. In this electrical lesson students build their own Emergency Radiation detector Electroscope.
Curated OER
Coulomb's Law and Induced Polarization
Engage your aspiring physicists in a series of lab activities directied at demonstrating the behavior of electric force. In completing these exercises, learners will explore Coulomb's and Gauss's Laws. Well-written directions to four...
Curated OER
TE Activity: Build a Charge Detector
Pupils examine how electrical force takes place between two objects by building an electroscope. They apply the electroscope to determine an objects' charge intensity and to see what factors influence electric force.

The Invention of Faraday Cage
Students demonstrate how Faraday's cage work by building their own electroscope. In this physics instructional activity, students explain how Faraday's cage work. They cite several applications of this principle in the real world.
