This illustration shows the circulatory system across 10 orders of magnitude. Using the conventions of visual perspective the image travels in one continuous “landscape” from the human scale at the top to the atomic scale in the foreground. Placing objects from the circulatory system in one frame clarifies the connections between components, highlighting the system’s reliance on structures at very different scales. This illustration won the 2008 Science and Engineering Visualization Challenge from NSF and Science magazine!
Scale ladders are diagrams that can quickly convey the size of the nanoscale by showing how objects are related by size. Using existing research on understanding size and scale, the Visualization Laboratory carried out a series of experiments to develop effective scale ladders as well as guidelines for their design and use. This diagram can be dropped as is into an exhibition graphic or used as a template and adapted for different content or graphical contexts.
To understand why the nanoscale is different, we need to appreciate just how small it is. One common way to represent the nanoscale visually relies on scale ladders, diagrams that show how objects are related by size. Using existing research on understanding size and scale, the Visualization Laboratory carried out a series of experiments to develop a scale ladder and guidelines for their design and use.
This is a card game which can be played with museum visitors. Visitors will learn the relative sizes of various objects. They compete against each other (or you) to organize their hand of cards into lists of objects from largest to smallest.
"Exploring Size - Tiny Ruler" is a hands-on activity investigating just how small a billionth of a meter is. Visitors attempt to cut a paper ruler down to a nanometer-sized sliver. They learn that nano is too small to see, and certainly too small to cut with a pair of scissors!
"Exploring Size - Scented Solutions" is a hands on activity illustrating how small nano is. By sniffing a series of diluted scent solutions, visitors discover that nano-sized particles may be too small to see, but they're not too small to smell!
At the Nanoscale is a static component that aims to show just how super small one billionth of a meter, or one nanometer, really is. A Billion Beads is an activity where visitors inspect tubes that hold quantities of one thousand tiny beads, one million beads, and one billion beads. To the naked eye, the tube containing one thousand beads appears nearly empty. Visitors see that the next tube, partially filled, contains one million beads. Finally, to compare, a four-foot tall container nearly full contains approximately one billion beads.
Three Drops is a full body immersive simulation that allows visitors to interact with water at three size scales using their shadows. At each scale, different physical forces can be observed. At the macro (human) scale, where gravity is the noticeable force, visitors are showered with water drops from a simulated shower. At the microscale--one thousand times smaller--where surface tension becomes more apparent, visitors play with a beach-ball sized water drop.
"Nanotechnology: What's the Big Deal?" is a video introduction to the Intro to Nanotechnology exhibition. Get a broad overview of the unique challenges and opportunities presented by nanoscale science, and dive into the super tiny scale of nanotechnology.
Changing Colors is an interactive exhibit that shows how some high-tech nanomaterials mimic natural phenomena. Super-small, light-reflecting structures—instead of pigments—on the wings of some butterflies create intense, iridescent colors. Nanoscientists have replicated this effect with layered, super-thin films. Watch the colors change on butterfly wings and thin-film slides as you move them beneath a light source, and discover how nanoscale structures can manipulate light and create color. Butterfly specimens deteriorate with heavy use, and may need to be replaced periodically.
