These two hands-on short activities for students in grades 3-5 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 objects look different at different magnifications.
  • Students will recognize that technology can aid in observing processes too small to be seen with the human eye.
