Electric-to-Heat Energy Conversion Device
Demonstrate the conversion of mechanical energy to
electrical energy that then leads to the production of
heat energy. A wonderful unit to have to teach concepts
of Ohm’s law, wire resistance and electrical power
loss in wires. Connect the terminals of the conversion
device to a hand generator, turn the crank, and the
supplied mechanical energy will be transformed into
electrical energy. The electrical energy then passes through the 5-ohm resistor and
heat is produced. A liquid crystal thermometer displays the temperature of the resistor
over a range of 10–56 °C. Your students will definitely feel how much work it takes
to raise the temperature of the wire by 10 or 20 degrees. Requires a hand generator.

Orion Science Basic Electricity
Investigate electrical laws with the high-quality
labeled board in the Basic Electricity kit from Orion
Science. Experiments include Ohm’s law, serial and
parallel circuits, Kirchoff’s rule and charging and
discharging a capacitor. All cables can be conveniently
stored inside the kit.

Ohm’s Law Experiment Set
A fantastic lab to show the relationship between
voltage, current and resistance. Students will easily
make the comparison between brightness of a
lightbulb and the amount of nichrome wire between
the clip leads of the circuit. Students will also “feel”
the change in the electric circuit’s resistance when
they power it with a hand generator. Verify Ohm’s law quantitatively by connecting a
voltmeter and ammeter to the circuit. Includes 470 mm of nichrome wire mounted on
a wood base, wire lead with lightbulb socket and alligator clips, miniature lightbulb
and one piece of replacement nichrome wire.

1-Farad Capacitor Demonstration
Teach principles in capacitance, energy conversion and potential
energy by storing the energy from a hand generator in
this palm-sized disk! Once energy is stored in the ingenious
capacitor, use it to temporarily operate electrical devices, such
as motors, lightbulbs and other electric circuits. The large
capacitance will provide charging and discharging rates that will be on time scales
that students can actually measure. Rated at 5 volts and 1 farad.

Electric Swing Apparatus with U-Magnet
Demonstrate how a current-carrying wire in a magnetic
field will be acted on by a force. Verify the Right-Hand Rule
by changing the direction of the current and observing a
corresponding change in the direction of the force. Then
generate alternating current with a hand generator to
produce a resonating swing that illustrates the basic principles
involved in making an electric motor turn. Includes
a swing holder, coated copper wire swing and a U-shaped
magnet. A support stand and clamp are needed to hold up
the swing and are available separately.

Electricity and Magnetism—Motors
Build a Simple Motor—Flinn
STEM Design Challenge™
By: The Flinn Staff
Challenge your students to build a
simple motor with only three components:
a battery, a piece of copper wire
and a strong magnet! In this design
challenge, students recreate a simple
model of Faraday’s device that operates
on the same electromagnetic
principles. Once success is achieved, science and art are combined as students
design and build a more creative motor. Includes magnets, batteries and copper wire.
Students may supply additional materials for their creations.
Complete for 10 student groups.

DC Motor Made Simple—
Super Value Laboratory Kit
By: The Flinn Staff
In minutes, students can build a simple
spinning motor using just a magnet,
copper wire and a 9-V battery. Once they
learn what makes the motor run, they can
experiment with various designs to see who
can construct the fastest spinning motor!
Excellent hands-on activity to introduce how
electricity and magnetism work to generate power. Includes Teacher Notes, reproducible
student handouts and all necessary equipment.
Super Value Kit is complete for 30 students working in pairs. All materials are reusable.
9-V battery and 9-V battery clip with alligator clip leads are required for each group and
available separately.
