Hands-on Activities and projects for human skin

Magnifying Glass

Let students examine their own skin with a magnifying glass.

Compare the skin surfaces of:
  • the back of their hand
  • the palm
  • finger prints

It Rubs Me The Wrong Way

Here's an interesting way to experience that famous saying.

Have a student close their eyes (or blindfold them if the temptation to peek is strong.)

They place both arms outstretched on a table in front of them - palms down.

Use a small index card or other firm flat object.

Run the card over their skin in the direction from their hands toward their shoulders. The card should be close enough to the skin to touch the hairs, but far enough it does not touch their skin.

The student states when they feel something and describe what they feel. Insist that you did not touch their skin.

Why could they feel it? (Answer, hair follices go through the epidermis.)

Explain the value of hair. When it stands straight up the hair follicles trap a small amount of hair that is warmed by your body heat. You have your own blanket of warm air. Who would benefit more from this: a human or a shaggy dog?

Why do we get "goose bumps?" (Answer: Skin around the hair follicle is raised as well.)

Pin Prick

A similar activity to this next one was also done in nervous system with differentiation.

Use two pins. With the person blindfolded place both pins about an inch apart on the palm of their hand. Ask how many they feel. The answer should be two.

Bring them closer together, about half an inch. Now how many do they feel? (Still two)

Now bring the two points about a quarter to an eighth inch apart. How many do they feel? They will feel only one pin. The two pins are stimulating the same nerve. As far as your brain is concerned, one nerve means one pin is touching it.

Look at the diagram on the skin worksheets to make this explanation more evident to the students.

Now, do it again on the point of the index finger. They probably will feel two distinct points because there are more nerves in the finger tips.

Touch the Tips

Here is another activity that demonstrates the increased sensitivity to the skin on the fingertips.

You will need objects with different textures. Here are a few suggestions:
  • pin point
  • soft, furry cloth like velour or velvet
  • rubbery surface like a squishy eraser
Have the student put both hands on a table or flat surface again. One hand should be palm up and the other palm down.

Brush each object VERY lightly on the skin over the knuckle. Have them describe it.

Then brush it over the skin of the finger tips. They should have a more definite sense of the objects' texture.

Learn the major skin parts on the skin worksheets

Epidermis

The epidermis is the top layer of skin that you see. Try to pinch it. You can not pinch just the epidermis with out getting some of the dermis beneath.

Dermis

The dermis is the layer of skin beneath the surface of the epidermis. The organs to the skin system are in the dermis.

Oil Glands

While these may be the sworn enemy with many teenagers struggling with acne, oil glands really are valuable. They keep the skin moist and healthy. Dry skin is actually more uncomfortable than oily skin.

Sweat Glands

Oh, pul leeze, who needs these?

Perspiration helps people and animals cool off so they don't get over-heated. It's your own personal air conditioning system.

If you haven't already, now might be a good time to mention the value of underarm deodorant.

Nerves

The nerves in the skin respond to two different types of stimuli. Can your student guess them?

(The answer is pressure and temperature.)

You may remember about motor nerves which send messages FROM the brain to the extremeties. No such nerves in the skin. These nerves only send messages TO the brain.

Blood Vessels

Yes, skin has its own blood supply. There are arterioles and venules taking blood to and away from the skin.

Subcutaneous Layer

This is a nice way of saying fat. Hey, you have to have some of it you know!

Check how much subcutaneous tissue you have beneath the skin of your knuckles. Compare it to the skin in the upper area of your arm.

Now, what would you like like if you didn't have ANY subcutanous fat?

Fat Cells

The fat cells provide insulation to keep the body warm. People who have a lot of body fat will sweat more. It would be similar to having extra layers of blankets.
