Heat & Temperature
Gas Model
Gas Model is a transparent plastic cylinder with bouncing balls activated by a vibrating plate. This exhibit demonstrates the properties of gas molecules, which gain energy when heated.
Where: Crossroads: Getting Started
Geysers
The timing of the eruptions of these geysers depends on water temperature and pressure.
Where: This exhibit is not currently on view.
Hot Spot
This curved mirror focuses both light and heat.
Icy Bodies
Like comets, these chunks of dry ice slowly disintegrate as they move, leaving a visible trail of condensed water vapor.
Skillets
Skillets heat up differently: test their mettle.
Watch Water Freeze
Ordinarily, water freezes too slowly to be appreciated. Here, polarized light and an ultra cold slab let you watch water crystalize rapidly in real time. The colorful mosaic of ice that forms is different every time.
What's Hot, What's Not?
At this exhibit, an infrared camera detects the heat radiating from warm objects and projects it on a big screen, allowing you to see what’s hot (and not) about you and the other people and objects in your surroundings.
