Do Now Heading: UV Radiation Pick up a sun safety pretest from the front table Begin working on it – There are no wrong answers.. I just want to see what you know about sun safety!

UV Light UV light can damage the human skin. Possible eye damage can result from high doses of UV light, particularly to the cornea which is a good absorber of UV light. Many things that are invisible to the human eye become visible under UV light. Sun tanning describes a darkening of the skin (especially of fair- skinned individuals) in a natural physiological response stimulated by exposure to ultraviolet radiation from sunshine (or a sunbed). A positive effect of UVB exposure is that it induces the production of vitamin D in the skin.

If UV Rays are so dangerous to us, how can we protect ourselves from them? Answer the question with at least 3 complete sentences as well as a picture to help support your claim.

Today’s Goal Come up with a hypothesis to test that relates to UV protection using UV Beads 1)Sunscreen 2) Clothing

UV Beads Each group will be given 10 UV beads. Using these beads you will construct your own experiment!

Possible Questions to Answer SunscreenClothing Does the amount of sunscreen have an effect on UV protection? Does the SPF on sunscreen have am effect on UV protection? Does thicker clothing protect us better against UV light than thinner clothing? Does the color of the clothing matter against UV radiation?

Conclusion As a lab group make a poster about how we can protect ourselves from UV radiation. Make sure that your poster includes 1)Your Essential Question 2)Data from your lab 3)Some suggestions you have for people who do not know how to protect themselves from UV radiation.
