Good Morning!
• Extra Credit-Extension Question is due- Act. 61 extension question(report)
• Draw a picture of Quantifying Energy- due tomorrow for 3 extra points
Act. 63
• Date: 5/21/13
• Challenge Question: How many calories are in a _____________?
• Getting Started: What are calories?
• How do you measure calories?
Examples of where calories are found
• Nutrition
• Weight
• Food
• Human body
• Minerals
• Drinks
• Water-flavored, sparkling, carbonated
Give examples of types of calories
• Food
• Drinks
• Water-certain types of water
• Example: sparkling water, carbonated water, flavored water
Glossary-Write definition in your own words
• 1. Calorie-
• 2. calorie-
• 3. calorimeter-
Glossary
• 1. Calorie- units being used= 1,000 calories
• 2. calorie- energy released to raise the temperature in grams of water
• 3. Calorimeter-a device that can measure the amount of calories in a food and amount of stored energy.
Materials pg. #
• Safety:
• Procedure: Steps # 1-7 will be demonstrated, you will record results in your data table
• This lab will be modeled
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

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