Unit F Quiz #2

Activity 98 Analysis Questions

Activity 99: Personal Protection Plan Please open your books to page F49.

Activity 99: Personal Protection Plan Looking at our warm-up list, we know there are some good things that come from exposure to UV. There is also increased risk to eyes and skin from excessive reflected UV. Skin cancer and cataracts are caused by more than just reflected UV light.

Activity 99: Personal Protection Plan With you table, come up with 4 factors that may increase the risk of too much UV exposure for humans. What kind of things cause more UV exposure? Are there factors that we cannot prevent? Ideas: where you live, what you do, choices you can make.

UV Risk Factors Childhood exposure: skin and eyes are most sensitive during childhood. Scientists estimate that 80% of sun damage occurs before age 20! Geographic location: sunlight intensity is greater at the equator. index.php?location=united%20states

UV Risk Factors Time of day: the peak period of most intense sunlight is 10:00am-3:00pm. Duration or frequency of activity: the longer/more often the activity, the higher the risk. Type of activity: indoor/outdoor sports, games, organizations, etc.

UV Risk Factors Family history: people with family members with certain skin may have a genetic-related issue with UV. Skin tone: people with naturally dark skin are at lower risk for skin cancer. Also, those with a lot of mole or freckles are at a higher risk. Clothing choice: hats, sunglasses, and sunscreen all reduce the risk of UV exposure.

Activity 99: Personal Protection Plan Part A: With your partner, read through the scenarios and evaluate their situation and UV risk. Rate each item as “low,” “medium,” or “high.” Part B: Evaluate your own UV risk and come up with a personal protection plan on the back of your “Assessing Ultraviolet Risk” paper.

Activity 99: Personal Protection Plan In the case studies you analyzed, who has the greatest risk for: Cataracts? Skin cancer? What risk factors are common for both cataracts and skin cancer?

Unit F Pre/Post-Assessment With your current knowledge of waves, answer the questions from the post- assessment to the best of your ability. DO NOT turn in; keep it at your desk!

Unit F Review: Some Helpful Hints Speed/Frequency/Wavelength Formula SPEED FREQUENCY WAVELENGTH

Unit F Review: Some Helpful Hints Transverse waves: can move in any medium or vacuum. Moves perpendicular to the medium Has crest/trough

Unit F Review: Some Helpful Hints Longitudinal waves NEED a medium to travel through; the push particles as they move (compressions and rarefactions.) Sound waves
