Indiana University of PA, Indiana, USA
Activity Time: 40 minutes
Concepts Taught: Adding Calories

Objective(s):

1. After learning the unit on calories, the students will be able to identify how many calories are in each gram of fat, protein, and carbohydrates with 100% accuracy.
2. After learning the unit on calories, the students will be able to look at a Nutrition label and calculate how many calories came from fat, protein, and carbohydrates with 90% accuracy.

Introduction to lesson

Today I want to ask you a couple of questions?
· Do any of you know what a food label is?
· How many of you when you look at a food label really understand what it means?
· Do you really understand the calories, like for instance where they came from?
· Do any of you understand what it means when it states that there is fat, protein, and carbohydrates in the item you are about to eat?
The reason I am asking you these questions, is because it brings us to today's lesson. We are going to learn exactly what the calories mean and how you measure the fat, protein, and carbohydrates.

Content/Learning/Subject Matter Activities/Experiences

1. Nutrients
Can anyone give me an example of a nutrient?

2. Macronutrients-
-They are needed in the body in large quantities
- They give caloric value
Example: Carbohydrates, protein, and fat

3. Micronutrients
- They are needed in smaller amounts
- They give no caloric value
Example: Vitamins and Minerals
Calcium, Niacin, Iron, Vitamins A, B, C, D, E, and K

4. Protein
- Main function is growth, maintenance, and regulation of body tissues.
- Helps build muscles, bones, and skin.
- When you calculate proteins they = 4 calories per gram
Show transparency on protein
- example: 4*4 grams of protein = 16 calories came from protein
-To find how many calories are in protein you multiply the # of grams x 4, because there are 4 calories in each gram of protein.

5. Carbohydrates
- Body's preferred source of energy
- Mislabeled as the "fattening nutrients"
- Two kinds of carbohydrates
- Simple (sugars)

- Complex (starch/fibers)
What kind of carbohydrate would a piece of candy be?
What kind of carbohydrate would pasta be?
- When you calculate carbohydrates they = 4 calories per gram
Show transparency on carbohydrates
-To find how many calories are in carbohydrates you multiply the # of grams x 4, because there are 4 calories in each gram of carbohydrate.

6. Fats
- It is the second major source of energy for the body.
- Needed for protection of vital organs, insulation of the body, transportation and storage of vitamins, and adds flavor and
-Texture to the food.
- There are 3 types of fat
- 1. Saturated-, which is solid at room temperature, comes from animals, and it increases your cholesterol level.
- 2. Monounsaturated- which is liquid at room temperature.
- 3. Polyunsaturated-, which is liquid at room temperature, and it, comes from vegetable oils.
- When you calculate fats they = 9 calories per gram
Show transparency on fats

To find how many calories are in fat you multiply the # of grams x 9, because there are 9 calories in each gram of fat.

7. Going over the food label

Pass out handout on the food label, and show transparency

8. In order to get the total number of calories you add the calories from the fat, protein, and the carbohydrates. Then you have the total number of calories in an item.

Show an example on the blackboard
- For example: If I had 27 calories from fat, 4 calories from protein, and 16 calories from carbohydrates, How many calories would be in this item?

Summary of Learning's (Review) of this Lesson/Closure

The students will now put all their handouts and notes away. The students will pair up into groups of three/four. I will pass out a worksheet and give each group a food label and the students will answer the questions regarding the food label. After everyone is finished we will answer and review the worksheet, and I will ask if there are any questions.

Assignment

Evaluation Procedure

Quiz at the end of the week. The student will know how many calories per gram come from fat, protein, and carbohydrates. They will also be able to calculate the calories by looking at a Nutritional food label.
