STATIC ELECTRICITY

Student Objectives and Activities 


Students will understand how static is created, how to tell if static electricity is present and will know some everyday examples. 

Suggested Teaching Strategies 

Begin with a teacher demonstration showing static electricity. Rub a balloon on your hair with students trying to figure out why the balloon sticks to the wall.
(The correct answer is not too much hair spray.) 

A second effective demonstration of static electricity is bending a thin steam of tapwater with a comb that had been charged by combing it through hair. 

Students are shown notes on Electricity and Static Electricity and understand how electrons are "rubbed off" certain objects or "stolen" to produce static
electricity. 

Next complete the activity "Lightning Never Strikes Twice" (The July 1993 National Geographic has especially good photographs of lightening that could
be used here.) 


*** Note ***
Teachers lacking hair should enlist a student assistant for these demos.
