Nano-size objects are smaller than the wavelength of light and because of this they cannot be viewed with a light microscope. Special tools are needed to see nanoscale objects, one of which is the scanning electron microscope. This activity will have students explore the types of images that can obtained using an SEM. Teachers may want to remotely access an SEM available on RAIN: or check with their local college or university.
