| A combination of macroscopic models, materials synthesis, and scanning microscopy exercises have been developed to help undergraduate students at Otterbein College visualize materials at the nanoscale. In a sophomore-level general studies course, students use scanning tunneling microscopy (STM) to generate images of the atomic structure of graphite. This laboratory module is the culminating activity in a quarter-long exploration of the strands of evidence leading to the conclusion that matter is made up of atoms. A series of exercises in General Chemistry centers on gold nanoparticles, their preparation, characterization by visible spectroscopy and scanning microscopy, and incorporation of nanoparticles into glass to make "stained glass". Nanotechnology in secondary education was also promoted by offering a five-day workshop for high school teachers with assistance from secondary science education majors at Otterbein College. |
