With the energy trainer, pupils quickly get the hang of energy: The handy case is
fi tted with a generator, which is operated via a crank handle. Various consumers
can be operated with the self-generated electricity. Pupils learn the differences
in energy requirements using their own exertions. How much more energy must the
pupil generate in order to power a halogen lamp, compared with an LED lamp? How
much power is required to heat a thermal resistor to 40 degrees Celsius? How much
power to play music through an active loudspeaker?
The new didactic learning
case from Christiani: ideal for teaching the basics of energy.
