• These hands-on activities for middle school students focus on measurement, scale and proportion (nanoscale and microscale) and nanotechnologies. These brief activities can be used in a classroom setting as well as informal education settings.

    Objectives:

    • Students will understand that magnifying objects allows them to be seen in more detail.
    • Students will recognize that objects look different at different magnifications.
    • Nanotechnology researchers are developing thin-film solar electric panels and nanowires to power mobile electronic devices. The nanowires will convert light, friction, and/or body heat into usable energy to power the devices. 
    • Although nanotechnology is a relatively new field of science, nanoscale materials have been used for centuries. Medieval churches used different sizes of gold and silver particles to create colors in their stained glass windows.
    • The microbes that inhabit a single person outnumber the human cells ten to one and can weigh approximately three pounds.
    • Streptococcus bacteria are responsible for most tooth cavities and are a leading cause of oral infections.
