  1. Good Morning! • Please have out and ready your journals and Science Books open to Act. 63 • Extra Credit-Extension Question is due- Act. 61 extension question(report) • Draw a picture of Quantifying Energy- due tomorrow for 3 extra points

  2. Act. 63 • Date: 5/21/13 • Challenge Question: How many calories are in a _____________? • Getting Started: What are calories? • How do you measure calories?

  3. Examples of where calories are found • Nutrition • Weight • Food • Human body • Minerals • Drinks • Water-flavored, sparkling, carbonated

  8. Materials pg. # • Safety: • Procedure: Steps # 1-7 will be demonstrated, you will record results in your data table • This lab will be modeled

  9. Use formula Step #8 • Energy released (calories) = temp. change of water (˚C) X Mass of water (g) Hint: 1 ml of water weighs 1 gram

  10. Step # 8 • 1. 3˚C x 100 ml = 300 calories • 2. ˚C x ml= calories • 3. ˚C x ml= calories

  11. Measuring Calories

  12. Step #9 • There are 1,000 calories in 1 calorie. • How many calories were in each chip: • 1. Ruffles • 2. FlaminHots 300 calories x 1,000= 3, 000 Calories • 3. Doritos

  13. Complete Analysis #1-6 • Extra Credit: bring in nutrition labels of your favorite snack (junk food) up to 3, write the formula, calculate it and look at the calories. Circle the snack with the most calories-Due Tues. May 28, 2013 • Picture of Quantifying Energy- 3 points due tomorrow 5/22/13
