## Series / Parallel Bulb Board

**Students can explore series and parallel circuits with one simple tool!**

No more wire nests! The five bulbs can be quickly arranged in series, parallel, or complex circuits, simply by adjusting the Bussbars. 5 mini bulbs included. 38cm x 13.5cm.

## Ohms Law Experiment Kit

Demonstrate the relationship between voltage, current, and resistance using this kit and a Genecon as a power source. Students will gain a better understanding of Ohm's Law as they alter positions of clip leads along a nichrome wire and observe changes in the brightness of the attached bulb. This qualitative approach can be made more quantitative by adding an ammeter and voltmeter to the circuit. The kit consists of a 450mm nichrome wire mounted on a wood base, a bulb, a socket, and alligator clip leads.

## Electric Swing Apparatus

**Study the interaction between a current-carrying wire and a constant magnetic field!**

The Electric Swing Apparatus, instrumental in promoting an understanding of Fleming's Rule and the production of alternating currents, includes a wooden swing holder, a coated copper wire swing, and a color-coded U magnet.

## Thermoelectric Device

**Heating or cooling with the turn of a crank!**

This fascinating accessory demonstrates the Peltier effect - the absorption or emission of heat energy when electrons move from one state to another across dissimilar semiconductor junctions. Just connect it to the Genecon, turn the handle in one direction, and the plate heats up. Reverse direction and the plate cools down!

Thermoelectric circuits such as this allow temperature control when size or economics make normal cooling techniques impractical. They are used on circuit boards to cool components and in picnic coolers powered by car cigarette lighters. For an added challenge, ask your students to suggest more important or diverse applications for the device.

## 1 Farad Capacitor

**The Arbor Scientific 1 Farad Capacitor Demonstration - An experiment in stored potential!**

With the The Arbor Scientific 1 Farad Capacitor demonstration students can study and understand electric potential, capacitance, and energy conversion. The Genecon's output can be stored temporarily in this unique miniature 1 farad capacitor, then tapped to perform various short-term tasks. The one farad capacitor uses revolutionary electrochemical technology to pack what once would have been a roomful of equipment into one palm-sized disk.

The Arbor Scientific 1 farad Capacitor is rated at 5 volts and 1 Farad.

## ElectroMagnet

Simply add current via the Genecon to visually demonstrate the relationship between electricity and magnetism.

With this electromagnet, your students can more easily visualize the relationship between electricity and magnetism. The large coils are perfect for applying the Right Hand Rule, so students can discover the direction of the magnetic field they cause. The horseshoe shaped, soft iron responds to the field by becoming magnetized only when you supply current. You can connect it to a battery, a transformer, or use the Genecon and have your students measure the amount of force they can create.

## Visual Electricity Demonstrator

**Help students visualize the flow of electricity!**

Exclusively distributed by Arbor Scientific, the Visual Electricity Demonstrator displays current generated by the Genecon or by batteries to help your students better understand the dynamic nature of electric current.

Bright, easy-to-see LEDs in the unit represent the flow of charged particles through the circuit as the Visual Electricity Demonstrator pulses to life. Connect it to a 1-Farad Capacitor (see below), and the unit demonstrates the charging capabilities of the Genecon, simulating the flow of electric current as it recharges and discharges.

If you're using the C.A.S.T.L.E. program, you're sure to find the Visual Electricity Demonstrator a valuable addition to your teaching tools.

**Extra Information**

Use the VED to show how charged particles are flowing in an electrical circuit. Show how the charged particles are stationary in an open circuit. Connect the VED to different sources and circuits to see how the flow of electric current is affected.

**A sample activity from the data sheet:**

Next, add the unit to the end of a circuit which has several light bulbs connected in parallel along with a power source (the Genecon and the parallel bulb base work well). Have the students predict if the current will increase or decrease as each light bulb is connected to the circuit. Explain the different results obtained with the two circuits. [more paths allow more current to flow]

**Science Standards**

In using this product, many of the national and states' science education standards are covered. Some examples are provided here. These are representative, however. Check with your state to find the exact standards.

Electricity in circuits can produce light, heat, sound, and magnetic effects. Electrical circuits require a complete loop through which an electrical current can pass.

- Describe charged particle flow in simple circuits.
- Demonstrate that electricity can flow in a circuit and can produce heat, light, sound, and magnetic effects

## Electrical Current and Field Kit

**Repeat Hans Oersted's classic demonstration**

This kit allows students to demonstrate that a magnetic field is created around a wire carrying an electrical current. The kit includes a transparent magnetic compass (for detecting the induced field) and insulated alligator clip leads. The transparent compass makes this an ideal overhead projector demonstration as well. Use the Genecon with the Electrical Current and Field Kit or the 1 Farad Capacitor Demonstration.

## Energy of a Photon Demonstrator

**Electricity Energy Demonstrator - Dramatically prove that different colors contain different energy potential!**

Light emitting diodes, LEDs, convert the energy change of one electron into one light photon. With the Energy of a Photon Demonstrator, slowly increase the energy of the electrons by increasing the voltage across the LEDs and you will see that the red LED comes on at the lowest voltage, then the green, and finally the blue at the highest voltage.
