S&S Activity 2.2: Modifications

  • Use this optional activity for students who are less experienced with systems at different scales.
  • Have students use the microscope to look at cells to get a better sense of scale.


  • Focus on the four benchmark scales (e.g., atomic-molecular) rather than the exact Power of Ten (e.g., 10-
    8m) for each picture.
  • The Powers of Ten with Pictures 11 x 17 Poster has images on the poster that are only to be referenced after this activity is completed, so make sure to wait until the end of the activity to post this version of the poster.
