Understanding Calories: Measuring Energy in Food and Drinks

In this lesson, we will explore the concept of calories, their role in nutrition, and how to measure them accurately. Students are required to bring their journals and Science books for an interactive discussion on energy quantification. Additional tasks include drawing a picture of energy measurement (due tomorrow), completing an extra credit extension question, and analyzing the calorie content of favorite snacks. This hands-on approach will help solidify your understanding of calories and their impact on the human body.

Presentation Transcript

  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

  4. Give examples of types of calories • Food • Drinks • Water-certain types of water • Example: sparkling water, carbonated water, flavored water

  5. Introduction

  6. Glossary-Write definition in your own words • 1. Calorie- • 2. calorie- • 3. calorimeter-

  7. 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.

  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
