Central Concept: The Electromagnetic Spectrum
Central Character: Dracula
A passage leads
to Dracula's Library, complete with oversized books and furniture
and a giant fireplace. A life-size cutout of the Prince of Darkness
himself greets visitors and introduces them to the properties
of light, waves and particles. Lessons on the electromagnetic
spectrum and its relationship to light are integrated into hands-on
activities. Visitors create "Quiet Lightning" by touching
a glowing plasma sphere, causing electrons to flow through a
combination of rare gases, demonstrating the conversion of high
frequency alternating current into electromagnetic waves.
The thermal imaging exhibit uses a special infra-red camera
to "photograph" the heat that objects, or in this case,
visitors, radiate. An attached computer system generates a vibrant
colorized video of the body temperatures, letting visitors "see"
the unseen. Even small heat variations from different parts of
the body are evident. Visitors learn about light particles by
powering lightbulbs in the radiometer exhibit, about polarizing
filters by making a bat appear and disappear. Dracula's interactive
computer station, housed in giant books, uses graphics, text,
images and sound to reinforce light and energy concepts.

Visitors touch a glowing plasma sphere to create a lightning-type
effect from the flow of electrons through a combination of 15
rare gases, demonstrating the conversion of high frequency alternating
current into electromagnetic waves.
Visitors spin a disc and see a bat image appear and disappear.
Polarizing filters demonstrate how light has characteristics
of waves. Filters are made up of very fine lines oriented in
one direction. Light waves pass between lines but when another
filter is placed at right angles (or perpendicular) to the original,
no light can pass through, making the bat image appear dark.
This exhibit demonstrates the particle-like qualities of light.
Visitors direct a light source toward several rows of radiometers.
When the photons of light strike the surface of the radiometer
sails they transfer their energy and cause the sails to spin,
creating a dramatic display of light and movement.
Dracula's Multimedia Computer Station
This interactive computer station, encased in giant books in
the library, reinforces the concepts explored in the Dracula
Library interactive exhibits through a question and answer format.
The concepts further explored in the computer interactive are:
- Energy manifests itself in many forms. Mechanical (potential
and kinetic), chemical, electrical, magnetic, nuclear and radiant
energy are all different forms.
- Energy can be transformed from one form to another.
- Evidence that matter has properties of both particles and
