#Built a sun spotter skin#
Skin cancer may first appear as a small spot on the skin. These may be cancerous (malignant) or harmless (benign). This growth can lead to clumps of extra cells called a tumor, or lesion. When UV light enters skin cells, it can harm the genetic material (called DNA) within.ĭNA damage can cause changes to cells that make them rapidly grow and divide. Too much sun exposure can also raise your risk for skin cancer, the most common type of cancer in the United States. As a result, your skin may develop more wrinkles and lines. Over time, UV damage can take a toll on your skin and its underlying connective tissue. Still, long-term damage to your skin can remain.Īs you get older, it becomes harder for skin to repair itself. Katz, director of NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases. “When you’re exposed to ultraviolet radiation, there’s a repair process that goes on constantly in each one of your exposed cells,” says Dr. Your skin may peel, but it usually looks normal in a week or 2. You might have noticed this type of skin repair if you’ve ever had a bad sunburn. The outermost layer of skin constantly sheds dead skin cells and replaces them. Your skin does have ways to prevent or repair such damage. Kramer, a cancer prevention expert at NIH. “The more sun exposure you have, the earlier your skin ages,” says Dr. Skin may even become thickened and leathery, wrinkled, or thinned like tissue paper. Over time, exposure to these rays can make the skin less elastic. When UV rays enter skin cells, they upset delicate processes that affect the skin’s growth and appearance. UVA rays can travel more deeply into the skin than UVB rays, but both can affect your skin’s health. Too much exposure to UVB rays can lead to sunburn. The longest of these UV rays that reach the Earth’s surface are called UVA rays. But shorter waves, like ultraviolet (UV) light, can cause problems. Long waves, like radio waves, are harmless to people. Sunlight travels to Earth as a mixture of both visible and invisible rays, or waves. Sunlight also helps our skin make vitamin D, which is needed for normal bone function and health. Getting too little sun, especially in winter months, can leave some people prone to a form of depression known as seasonal affective disorder. Sunlight helps keep our sleeping patterns on track so we can stay awake by day and sleep soundly at night.

W atch the video from the Geophysical Institute that goes with the instructional diagram below. You can build a sunspot viewer for your group with a pair of binoculars and cardboard.
The larger sunspot viewer might be a better option for a group to sit around the screen and draw their observations. This pinhole viewer is a personal viewer only one person can look through at one
#Built a sun spotter how to#
You can also learn to build one yourself! Watch this video from Boy's Life Magazine on how to make a shoebox pinhole viewer. Of the North hereand includes a booklet of activity ideas. If you are in the Fairbanks area the Sunspotter can be borrowed from the UA Museum Here are prompts to use with the Sunspotter.This activity from Cultural Connections goes with the Sunspotter and can be used with either viewer.You can use this sun map grid sheet to help place the sunspots. Observe the sun over time like Galileo did! Set up your sunspot viewer or grab your pinhole viewer and make a daily sketch of.Track sunspots as a classĪnd learn how scientists who study the aurora use solar flares to predict the northern How sunspots change over time, and draw their observations. Students can predict how the sun will look, observe It gives students the chance to gather data about the sun like scientists have throughout the centuries. The Sunspotter uses lenses and mirrors to show a projection of the sun’s image so Sunspotter Warning: Never look directly at the sun.
