Evaluating Sunscreens Lab Preview Directions: Answer these questions before you begin the Lab. 1. Why are terms like sunblock and waterproof misleading? Hands-On Activities 2. Why is it important to calculate the cost per milliliter of each brand of sunscreen? Without protection, sun exposure can damage your health. Sunscreens protect your skin from UV radiation. In this lab, you will draw inferences using different sunscreen labels. Real-World Question How effective are various brands of sunscreens? Materials variety of sunscreens of different brand names Goals Draw inferences based on labels on sunscreen brands. Compare the effectiveness of different sunscreen brands for protection against the Sun. Compare the cost of several sunscreen brands. Safety Precautions Data and Observations 1. 2. 3. 4. Brand Name SPF Cost per Milliliter Procedure 1. The Sun Protection Factor (SPF) tells you how long the sunscreen will protect you. For example, an SPF of 4 allows you to stay in the Sun four times longer than if you did not use sunscreen. Record the SPF of each sunscreen on the data table below. 2. Calculate the cost per milliliter of each sunscreen brand. 3. Government guidelines say that terms like sunblock and waterproof are misleading because sunscreens can t block the Sun s rays, and they do wash off in water. List misleading terms in the data table for each brand. Misleading Terms Atmosphere 5

(continued) Hands-On Activities Conclude and Apply 1. Explain why you need to use sunscreen. 2. Evaluate A minimum of SPF 15 is considered adequate protection for a sunscreen. An SPF greater than 30 is considered by government guidelines to be misleading because sunscreens wash or wear off. Evaluate the SPF of each sunscreen brand. 3. Discuss Considering the cost and effectiveness of all the sunscreen brands, discuss which brand you consider to be the best buy. Communicating Your Data Create a poster on the proper use of sunscreens, and provide guidelines for selecting the safest product. 6 Atmosphere

3 Enrichment Thermals Meeting Individual Needs Convection is responsible not only for major wind systems that affect the entire Earth but also for small-scale air movements that affect only a small part of Earth s surface. Land and sea breezes are an example of small-scale air movements, or local winds. These small-scale movements are the result of differences in temperature over land and sea. Small Scale Movement Thermals are another type of small-scale movement. Thermals develop over only a few hundred square meters of land and last less than an hour. The formation of thermals is illustrated in the pictures below. Figure 1 shows the thermal beginning as a rising column of air at Earth s surface. In Figure 2, a cap develops at the top. Eventually, the cap breaks off and increases in size as it continues to be forced upward (Figures 3 and 4). At higher altitudes, the thermal develops a donut shape before it dissipates in the cooler air (Figure 5). Thermals may develop where Earth s surface is warm and the overlying air is cool. This may occur anywhere on Earth. The amount of heating at the surface varies, depending upon the amount of solar radiation absorbed by that part of Earth s surface. Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 1. Thermals occur as a result of hot and cold air movements: air rises and air sinks. 2. What eventually causes a thermal to dissipate? 3. Vultures and hawks sometimes glide the thermals. What do you think this means? Why do you think they do it? 28 Atmosphere
