Resistance in Wires—
Super Value Laboratory Kit
By: The Flinn Staff
Students will observe the brightness of a lightbulb to determine how these wire
variables affect the current in an electrical circuit. Then they will heat up a wire and
see the effect that temperature plays on the resistance in a wire. Will the resistance
increase, decrease or stay the same? This engaging experiment will help students
learn about simple circuits, resistance, current and Ohm’s law. Includes detailed
instructions, a reproducible student worksheet and Teacher Notes with sample
answers and teaching tips.
Super Value Kit is complete for 8 student groups. All materials are reusable except
for the 28-gauge wire, which is available as a refill. 1.5-V batteries, battery holder and
Bunsen burners are required and available separately.

Resistance Mystery—
Super Value Laboratory Kit
By: The Flinn Staff
In this two-part “mystery” analysis, students first decode the color bands on a series
of nine unidentified resistors to predict their resistance values. They then test their
predictions by placing the resistors in series and parallel circuit combinations and
measure the current and voltage. Students see how resistors help control the current
to circuit components and split voltage to bring power to multiple components.
Super Value Kit is complete for 15 student groups. All materials are reusable.

Resistance Board
This resistance board is conveniently wired so every student can have his or her
own unknown resistance. You can quickly assign a unique number combination for
each student. This set of nine precision resistors is ideal for use with a wheatstone
bridge or other resistance measuring experiments. The resistors are mounted on a
PC board with a binding post at the end of each resistor (nine on the periphery, one
at the center). This layout allows any two resistors to be wired in series. The values
of the resistors are unknown to students but are provided in the included Teacher’s
Instructions.

Resistance Board
AP5702
Wheatstone Bridge
This classic experimental device compares a wire with known resistance to a wire
with an unknown resistance and then uses a simple mathematical formula to
determine the unknown resistance. You need a galvanometer (AP9230) to indicate
the exact spot on the “slide-wire” device when the current ceases to flow and the
bridge is balanced. Resistance coil (AP5701) and resistance board (AP5702) are ideal
sources for unknowns for your experiments. Unit comes assembled with detailed
directions and background.

What Is a Capacitor?
Super Value Laboratory Kit
By: The Flinn Staff
Students investigate the properties and function of capacitors by using them to build
and test simple circuits. By connecting a known capacitor in series with different
resistors and a light-emitting diode (LED), students discover how a capacitor stores
and releases charge and electrical energy.
Super Value Kit is complete for 15 student groups. All materials are reusable.
Multimeters and connecting cords are required and available separately.
