I think this is a great design that can be introduced in electrostatics and be carried all the way through to circuits.
Small groups can work together setting up and charging this low-cost capacitor. We took two metal plates, 10cm square, and bent back the bottoms to provide for stand-up support and binding posts. You attach grounding wires or electroscope connections to the plates. Easy-to-use instructions walk your students through the process.

This is a good commercial electrophorus and is similar to the student made ones you'd encounter in the static labs in the Science Joy Wagon workbooks.
Produce a strong spark repeatedly, without recharging. When surfaces are clean and the humidity is not excessive, sparks 6mm long can be produced over many days after the initial charging. The base is thick plastic with four rubber feet attached for convenient handling. The plastic material produces a strong frictional charge when rubbed with fur or other material. This charge is held for long periods. Its flatness and high rigidity also insure minimum separation and maximum induction, between the dielectric and the removable plate. The 18cm diameter aluminum plate is designed to eliminate any sharp edges which could cause leakage. This, combined with its high capacitance due to size, permits it to acquire and transport substantial charges. An insulating handle is attached. For charging, a fur friction pad is recommended, but not included. With instructions.

Ideal for a wide variety of experimental situations, a knob on top of the stopper accepts a charge. When the charge enters the flask, the aluminum leaves separate. How much the leaves separate depends on the size of the charge. There’s no easier way to teach or observe this phenomenon.

With sparks of 8" to as high as 12" to 15", yet a maximum continuous current of just 10 microamps, it's quite safe for classroom use. Check out the Van de Graaff accessories that will add excitement and interest to your demonstrations:

Our small Van de Graaff Generator stands less than 20 inches tall, but can produce voltages of up to 200kV and 5cm sparks only seconds after startup, at a great price. Years of manufacturing experience have been incorporated into this design that gives reliable results in all humidity conditions. The generator’s unique feature — a long clear insulating column — allows students to view the machine’s operation for a more spectacular demonstration and a greater understanding of how the instrument works. Large, 21cm polished dome collects large charges. Includes operation manual. 110V

Get two meters for the price of one! Analog student meter measures voltage or current! Just slide the terminal cover to convert from volts to amps.  Lightweight, portable, and convenient. This unit has a special safety feature that prevents mis-wiring by students. The auto switching mechanism covers the unused terminals for volts or amps when the other is in use. The meter also makes clear which function is in use when the switch is moved. Dimensions: 6.5 cm x 11.3 cm. Voltage range: 0-100mv-1v-10v-50v. Amperage range:0-100µA-100mA-1A-5A.

I found a pair of these very useful for demonstrating motor/generator relationship, including work and energy loss. Ideal as a battery replacement for a wide variety of basic electricity experiments, the Genecon generator is a low voltage power source that lets you create electrical current by simply turning a crank. This ingenious device generates student interest as well as 5 volts of direct current - producing electrical energy through hands-on student effort. Students enthusiasm is immediate, whether they are third graders lighting a bulb or college students reviewing sophisticated principles such as Ohm's Law or the electromagnetic properties of various materials. Made from a sturdy, see-through ABS resin with nylon-plastic gears and handle, the Genecon is designed to shrug off use and abuse. It produces approximately 200mA of usable current. You can reverse polarity by simply cranking the handle in the opposite direction. And, when powered by another Genecon or low voltage power source, it acts as a motor. Conduct dozens of exciting, hands-on experiments with the Genecon and its accessories:

Watts Up PRO includes all the displays of the standard Watts up? meter but also comes with software and USB PC interface. The software automatically graphs all data and includes an integrated analysis tool, called the Payback Calculator, which automatically calculates the time required for a new energy efficient appliance to pay for itself. Monthly savings are calculated and then are compared to the purchase price of the new appliance. As a data logger, the PRO records all data into non-volatile (stored even if power is lost) memory. Over one thousand data points can be stored, starting with a sampling rate resolution of one second. The sample rate is user selectable or can be automatically set (resolution decreases over time) so years of usage can be accurately recorded. The included cable allows for USB port connection of a PC and when used with the included software, data can be quickly downloaded to a computer where the software creates a data table and easy to manipulate graphs. The data and graphs can than be exported to popular spreadsheet and word processor programs for further analysis. Note how the graph at the right identifies the defrost cycle on a refrigerator. Watts Up PRO also records any power interruptions, which is extremely handy when performing an audit of several devices. In addition, the Pro is capable of real time logging when used with the additional Real Time Software (not included). 120v 60hz.
