Author(s): Nancy P. Moreno, PhD, Barbara Z. Tharp, MS, and Judith Dresden, MS.

Measuring and Protecting Skin

This activity uses guided inquiry to build students’ awareness of skin by having them compare and contrast the “skin” of an orange to human skin. Students will make observations and predictions, estimate, calculate, graph, and draw conclusions based on their investigation. 


  • Skin is a vital part of the body. 
  • Skin must be protected from sun damage.
