Electrostatics Kit
By: The Flinn Staff
Demonstrate static electricity using a variety of
easy-to-use materials. Kit contains three friction rods and pads (silk, flannel and fur)
for creating friction, three balloons and 10 feet of string. Complete instructions for
use are provided.

Investigating Static
Electricity—Super Value
Activity-Stations Kit
Four mini-lab stations are set up around the classroom, each a self-contained activity
focusing on a specific topic.
• Sticky Charges—Students investigate positive and negative electric charges and
observe how like and unlike charges behave.
• The Mysterious Moving Board—Students will be amazed as they discover how an
uncharged insulator can be “mysteriously” attracted by a charged object.
• Ready, Set, Charge!—The interaction of charged pith balls help students distinguish
between charging by conduction and induction.
• Curving Water—As students observe the effect of an electric charge on polar
molecules, they have fun seeing just how far the stream of water will bend.
Kit includes complete instructions with reproducible student handouts and valuable
Teacher Notes.
Super Value Kit is complete for 12 student groups. All materials are reusable!

Electrostatics—
Multi-Demonstration Kit
By: The Flinn Staff
Teach the basic principles of electrostatics using this comprehensive, all-in-one kit
that contains all the equipment needed for five demonstrations!
• Charging a Flask Form Electroscope—Verify the existence and properties of static
electric charge. Demonstrate charging the electroscope by conduction and by
induction.
• Electrophorus and Condensing Electroscope—Show how much greater amounts
of charge can be stored using an electrophorus and a condensing electroscope.
• Charge Distribution and Discharge—Use two condensing electroscopes to show
how charges distribute and how a lightning rod works.
• Faraday’s Cage and “Ice Pail”—Show students how charge accumulates on the
outside of a conducting shell.
• Curving Water into a Beaker—“Bend” a stream of water using an externally charged
object, proving that water molecules are polar.
Includes detailed instructions and reproducible student worksheets for each
demonstration.

Make a Positive Charge
Rub a solid glass friction rod with silk.
The glass rod will become positively charged.
Make a Negative Charge
Rub a hard rubber friction rod with animal fur or wool.
The rubber rod will become negatively charged.
Electrophorus
By: The Flinn Staff
Demonstrate laws of electrostatic induction,
generate and store large electrostatic charges and effectively transfer charges with
this classic device. Simply rub the acrylic plate with fur or silk to build up a charge.
Then holding the insulated handle, induce a charge from the acrylic plate onto the
aluminum disk. The disk can then be moved to transfer the charge to an electrostatic
device, such as an electroscope or Leyden jar. The built-up charge will continue
on the acrylic plate so you can return with the aluminum disk repeatedly without
recharging the plate.
Apparatus includes aluminum disk with insulated handle, charging plate and
complete instructions. Charging materials not included.
