This exhibit explores the amount of fuel needed to power an everyday need - light. Visitors pile chunks of coal onto a scale which, in turn, lights the bulbs, one by one. Geiger Counter Visitors rotate a large Lazy Susan-like disc containing everyday objects to a Geiger counter. The Geiger counter's clicking sound indicates radiation emissions from the common objects, demonstrating varying radiation levels in objects of everyday life. Energy can be transformed from one form to another.
Some energy is lost in the form of heat, making some of it unavailable for further useful work.
Matter can be converted to energy. Enormous amounts of energy can be involved in this conversion process.
