Purpose To develop an understanding of the science behind keeping skin healthy, including how it functions to protect the body and what can be done to protect skin cells from mutations caused by excessive sun exposure.

Context This lesson is part of the Skin Deep Projectwhich examines the science behind skin. For more lessons, activities, and interactives that take a closer look at the science behind skin, be sure to check out the Skin Deep Project page. This lesson is the first of two lessons about skin cancer using the SCI: Skin Cancer Investigation interactive.

In the first lesson, Skin Cancer 1: Exposing Healthy Skin to the Sun, students are introduced to the science behind keeping skin healthy including how it functions to protect the body and what can be done to protect skin cells from mutations caused by excessive sun exposure.

Types, Prevention, and Detection explores what happens when healthy skin cells mutate and grow uncontrollably, leading to skin cancer. This lesson continues use of the Skin Cancer Investigation interactive by beginning with "Skin Cancer: They may be unaware that it is the largest organ in their body.

The human adult is covered in about 22 square feet of skin. However, students are usually very aware of skin problems, particularly acne and other blemishes as they relate to physical appearance. High-school students may be particularly curious about the causes and prevention of skin problems but have little knowledge about skin cancer.

The Skin Deep Project takes advantage of this curiosity by introducing students in grades 6 through 12 to the science of skin, its role in protecting the body from invading microbes, regulating temperature, and sensing the environment. They will learn about the layers of healthy skin and what happens when healthy cells mutate and grow uncontrollably.

In addition to the interactive, students using this lesson will access the online book The Science Inside the Skin for in-depth information about the science of skin.
