Static Electricity Workshop

Learning Cycle Activity Groups: White Boards
or Discussion

1. What is Static Electricity?
Engage/Explore:

Balloon activity - Rub balloon on hair/shirt and stick it on the wall.

See http://www.as.wvu.edu/coll03/phys/www/rotter/phys201/6_Electricity/Electrostatics.htm for the following numbered activities:
2.1-2.6 Tape on table
See http://www.as.wvu.edu/coll03/phys/www/rotter/phys201/6_Electricity/Magic_Tape.htm for another version of this lab.
How many kinds of charge? Prove it how? See http://www.as.wvu.edu/coll03/phys/www/rotter/phys201/6_Electricity/Cash_or_%22Charge%22.htm.
Draw cartoons of charges for balloon, for tapes.

Explain:
Model of atom and charging objects.
See http://www.school-for-champions.com/science/static.htm for simple explanation. Re-do balloon cartoon.

Apply:

3.1- 3.2: Build electroscopes.
See http://www.engr.uky.edu/~gedney/courses/ee468/expmnt/escope.html for classic one.
See http://www.glenbrook.k12.il.us/gbssci/phys/mmedia/estatics/esn.html for animation of charging.
Try different materials. Make own triboelectric list.
Compare with http://www.school-for-champions.com/science/static_materials.htm.

2. How can charges be stored?
Explore:

4.1 - 7.3: Build electrophorous. Charge by conduction.
Charge by induction.
See http://www.as.wvu.edu/coll03/phys/www/rotter/phys201/6_Electricity/Electrostatic_Induction.htm for diagrams & explanations.

8.1 - 8.6: Use neon bulb to determine + or - charges.
8.7 - 8.8 group draw cartoon steps of charging.

Explain:

Build Leyden jar (capacitor) with film can.
See http://www.exploratorium.edu/snacks/charge_carry.html for insructions.
Charge with electrophorous.
See http://micro.magnet.fsu.edu/electromag/java/capacitor/index.html for animation of charging capacitor.
Build dissectible Leyden jar with plastic cup and 2 Al foil cupcake liners.
Charge, disassemble, reassemble it. Explain Leyden jar charging.

Apply:

Van de Graaff generator.
See http://www.mos.org/sln/toe/construction.html for history and animation.
See http://www.amasci.com/emotor/vdg.html for useful hints.
Charged objects: He balloons, soap bubbles
Electric Field: Puffed rice, hair (stand on insulator), disposable Al pans, fluorescent bulb (orient along field line).
See http://www.as.wvu.edu/coll03/phys/www/rotter/phys201/6_Electricity/Electric_Forces_and_Fields.htm for discussion and diagrams of fields.
See http://www.amasci.com/electrom/statbotl.htmlfor simple field-viewing bottle. (Be sure to see electrostatic, not magnetic.)
Wimshurst machine
Charges both + and -.
See http://www.coe.ufrj.br/~acmq/electrostatic.html for explanation and construction.
Explain VdG. examples.
Discuss misconceptions at http://www.amasci.com/emotor/stmiscon.html.
Safety with lightning/static electricity.
Discussion: uses of static electricity.
Discussion: dangers of static electricity.

3. Further construction projects:

Electrostatic generator.

Electrostatic motor.
See http://www.amasci.com/emotor/emotr2.gif for instuctions.
Or, simply move 2x4 board or coke can. See http://www.as.wvu.edu/coll03/phys/www/rotter/phys201/6_Electricity/2x4_Electroscope.htm.

Ridiculously sensitive charge detector.
See http://www.amasci.com/emotor/chargdet.html for construction.
