Contemporary chemistry, physics, as well as biology frequently deal with the structure of matter at nanoscale level. One of the most important techniques used for imaging and measuring surfaces at the nanoscale (sometimes even with atomic resolution) is the scanning probe microscopy (SPM). SPM is an important up-and-coming technique in both academic sphere and industry. For this reason, concepts underlying SPM should be mentioned in secondary education, at least for students with an interest in science and technical subjects. In order to introduce SPM into secondary science education, various teaching approaches might be followed. In this contribution, special attention is paid to simple models and analogies of SPM to illustrate the basic SPM principles.
