PURPOSE: Model of battery with electric circuit attached.
DESCRIPTION: This funny little gizmo is really used by some instructors as a model of an electric circuit attached to a battery. The "battery" raises the penguin "electrons" to a high potential. where they then progress through a "circuit" as they lose their potential. This model might indicate that a battery EMF provides energy which the carriers dissipate against resistance - the carriers do not speed up as they lose potential energy.
SUGGESTIONS: Mention that the toy is powered by a real battery. Place each carrier about six steps below the preceding to get uniform current.
REFERENCES: (PIRA unknown.)
EQUIPMENT: Toy model of "electric current with battery."
SETUP TIME: None.
