144 Unit 2 Nutrition and Wellness Copyright Goodheart-Willcox Co., Inc. Mini Lab: Evaluating Beverage Choices Looking at the Sugar in Drinks This lab involves using a kitchen scale to weigh the amounts of sugar in various portions of common beverage choices. If a scale is not available for each lab group, sugar can be measured in teaspoons rather than grams. If using this measurement method, you will need to keep in mind that 1 teaspoon (5 mL) of sugar equals 4 grams. 1. Create an observation sheet identifying your assigned beverage. Make a 5-column table, heading the columns with the following labels: Portion Size, Amount of Sugar, Calories, Walking Time (minutes), Walking Distance (miles). 2. Use a permanent marker to label three small zip-top plastic bags with your lab group’s assigned bever- age. Also label each of the bags with one of the specified portion sizes for your beverage. 3. Using product information provided by your teacher, calculate the amount of sugar that would be in a 12-ounce (355 mL) serving of your beverage. Record this amount in the appropriate space in your observation table. 4. Set your scale for grams. Place a small bowl on the scale and press the tare button. This will allow you to measure the weight of the sugar without including the weight of the bowl. 5. Weigh the amount of sugar you calculated in Step 3 and carefully pour it into the bag labeled 12 ounces. 6. Place the empty bowl back on the scale. Calculate and record the amounts of sugar in the other two specified portion sizes for your beverage. Then weigh those amounts and pour them into the appropri- ately labeled bags. 7. As a pure carbohydrate, sugar provides 4 calories per gram. Calculate the number of calories provided by the sugar in each portion size of your beverage and record your calculations in the appropriate spaces in your observation table. 8. Place an empty bag on the scale and press the tare button. Remove the bag from the scale and weigh the bag of sugar labeled male, provided by your teacher. Record this amount on your observation sheet as the recommended daily limit for added sugars for a teen male. 9. Repeat Step 8 with the bag of sugar labeled female, provided by your teacher. 10. Walking at a moderate pace (3 miles [4.8 km] per hour), a 150-pound (68 kg) male burns about 4 cal- ories per minute. A 120-pound (54 kg) female burns about 3 calories per minute. Calculate the number of minutes a male and female would need to walk to burn the calories provided by the sugar in each portion size of your assigned beverage. Record your calculations in the appropriate spaces in your observation table, separating the male calculations from the female calculations with a slash (/). 11. Each minute of walking equals a distance of about 0.05 miles. Calculate the distance a male and female would need to walk to burn the calories provided by the sugar in each portion size of your assigned beverage. Record your calculations in the appropriate spaces in your observation table, again separating the male calculations from the female calculations with a slash (/). 12. Compare your observations with those of the other lab groups. Then answer the following questions: A. Looking at the amounts of sugar in 12-ounce (355 mL) servings, how did your assigned beverage compare with other beverages? B. How did the amounts of sugar in common portions of your beverage compare with the recom- mended daily limit for added sugars for teen males and females? C. What did you find most surprising about the findings in this activity? D. What impact will these findings make on your future beverage choices?
