  1. Demonstrations The Integumentary System Skylar, Ansley, and Rayne

  2. Try these activities to find out what really happens in your Integumentary System!

  3. The Strength of Hair • Hair is amazingly strong, with a tensile (pulling) strength greater than steel wire of the same thickness. • Pull on a long piece of scalp hair. • Compare its strength to cotton thread, which is about 100 times thicker?

  4. Sweat Surprise! • Put a clear plastic bag over your and for a few minutes, tied loosely at your wrist. • Watch as tiny water drops form inside the bag as sweat evaporates from your skin and condenses on the plastic. • Why is this? Your skin constantly releases a small amount of sweat, even if you stay still.

  5. Thickness of Your Skin • Gently pinch a fold of your skin on the back of your hand between your thumb and your forefinger. • Your skin is about half of this thickness. • Try this on various body areas. • Where is your skin the thickest?
