Introduction to the concepts of electricity, electric charge, electric and magnetic fields, voltage, current and resistance, electromagnetism, law of electromagnetic induction and its applications.

The series of experiments in this demonstration introduces students to the concepts of electric charge, static electricity, electric force, electric field and voltage, electrical resistance, electrical conductors and insulators.

Students will experiment with static electricity, visualize the electric field, explore series and parallel circuits and Ohm’s law and will probe the difference between conductors and insulators and discover practical applications of electric current.

Finally, students will tackle such everyday questions as why our hair stands on end when we pull off our beanie hat or why we get a shock when we touch a doorknob or any other metal object. 2nd grade of Lyceum students will further explore the interactions of electricity and magnetism through experiments that demonstrate how electricity is generated and how electric motors work.
