Students will examine the order of size of objects from the nanoscale to macroscale to visualize exponents and decimals, make size comparisons of objects, and develop an understanding of how small a nanometer is in comparison to common objects. This lesson uses the metric system.
What You Can’t See Is All Around You. Mysteries of the Unseen World will transport audiences to places on the planet they've never been before, to see things that are beyond their normal vision yet are literally right in front of their eyes. Existing and emerging technologies are giving science exciting new images of long-hidden worlds—allowing viewers to see things not visible to the naked eye. Using high-speed and time-lapse photography, electron microscopy, and nanotechnology, one can peer into these invisible realms of things too fast, too slow, and too small to see.
Flip between macro and nanoscale images of familiar objects to learn about ways that nanotechnology is inspired by nature, surprising properties at the nanoscale, and new applications in nanotechnology. Includes print your own cards.
This program demonstrates the importance of scale (macro vs. micro vs. nano) and surface features in materials science and nanotechnology. Visitors will examine three different slides macroscopically (with their eyes) and microscopically (with a microscope). Each of the three slides has different size particles on its surface: macro, micro, and nano. The visitors predict how a drop of water will behave on each surface and then test their prediction.
