Measuring Calories Lab and Carbon Footprint Project Overview

This document outlines the activities for today's class, focusing on Act 61 data table and analysis, the Carbon Footprint Project, and a lab on measuring calories. Students are to prepare by having their journals ready. Extra credit opportunities include additional questions related to calorimetry and evaluating nutrition labels from snacks. The session will define calories, explore their significance in nutrition, and utilize calorimetry to quantify energy content in various food items. Ensure to follow safety procedures and record results accurately during the lab.

Presentation Transcript

  1. Good Afternoon! • Please have out and ready your journals open to Act. 61 Data Table & analysis #1-6 pg. D-46 • Take out Agenda-Carbon Footprint Project • Extra Credit-Extension Question is due- Act. 61 extension question(report) due Monday 5/19/14

  2. Act. 63: Measuring Calories • Date: 5/14/14 • Challenge Question: How many calories are in a ____________cheese puffed snack_(cheeto)? • Getting Started: What are calories? • How do you measure calories?

  3. What are calories? • F- satured fat • A-sodium • G-the amount of fat contained in your body • E-the amount of energy in food • B-same as G • C-the fat in food • D-fat

  4. How do you measure calories? • A-scale • F-keep track of what you eat • D-doctor checkup • C-burning

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

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

  7. Introduction

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

  9. 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.

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

  11. 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

  12. Calculating Calories • 1.- Cheetos- ___1__˚C x __100____ g = __100___calories • 2. Doritos - ˚C x ml= calories • 3. Takis -˚C x ml= calories • 4. Lays- • Formula : • Energy released (calories) = temp. change of water (˚C) X Mass of water (g) Hint: 1 ml of water weighs 1 gram

  13. Step #9 • There are 1,000 calories in 1 calorie. • How many calories were in each chip: • 1. Ruffles: • 2. FlaminHots : _100____calories x 1,000= 100,000 Calories • 3. Doritos:

  14. Measuring Calories

  15. Energy Released(calories) = temperature change of water( C) X Mass of water (g) 1 ml of water weighs 1 gram Follow formula to find energy released

  16. Extra Credit • 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
