In this materials science activity, students zoom in on the atoms in a soda can to explore the structure of materials. As they zoom, a vertical scale and labels in the images show the scale at which they are viewing the can. Once they have zoomed in on the can, students can drag a pointer on the adjacent vertical scale to access information, images, and video clips of scientists talking about the different scales represented. At the smallest scale (the atomic level), students read how scientists use the atomic force microscope to image the surface of atoms. At the largest scale (that of a human child), the properties of aluminum and the manufacturing of soda cans are described. Copyright 2005 Eisenhower National Clearinghouse
