Pores are tiny openings on the surface of the skin. Sweat glands are small coiled tubes in the dermis that carry sweat to the surface of your skin through pores helping to cool your body when it is hot. Melanin is a substance in the skin cells that controls hair and skin color. The amount of melanin in your body is hereditary. Those with darker skin have more melanin.
Freckles are small spots of melanin.
Place different objects in a bag. Ask students to feel the objects without looking at them. Draw a cross-section of the skin, labeling the dermis, epidermis, oil glands, fat cells, pores, sweat glands, and melanin. This Classroom Connector addresses Instructional Objective 1.04. One of our sensory organs is right up front and center of our faces.
