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 datasheet:
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
