P731: Macro micro nano: Exploring scale and surface chemistry

Tracy Jane Puccinelli, Anne Lynn Gillian-Daniel, Greta M. Petersen (University of Wisconsin – Madison, USA)

The Interdisciplinary Education Group (IEG) at the University of Wisconsin – Madison Materials Research Science and Engineering Center (MRSEC) has developed a K-12 outreach activity that demonstrates the importance of scale (macro vs. micro vs. nano) and surface features in materials science and nanotechnology. Visitors examine several different slides macroscopically (with their eyes) and microscopically (with a microscope). Each of the slides represents surface features that fall within one of three different size scales: macro, micro, or nano. The visitors predict how a drop of water will behave on each surface and then test their prediction, promoting inquiry-based learning.
