Measuring and Protecting Skin

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

What Has Skin?

To focus students’ attention, begin by asking, Do trees have skin? Then ask, What other things have skin? Expect a wide range of answers. Some examples might include tree bark, skin on a banana, lizard skin, bird skin, etc. List student ideas on the board. Older students may record the list in their science notebooks.

Discuss the purposes of skin, based on the class list of things with skin. Then ask, Is our skin similar to the skin of an orange? Hold up an orange and explain that students will examine the skin of an orange and compare it with their own skin.
