Diet and Exercise Journal
AUTHOR: Melissa Mendoza
DATE LESSON TO BE TAUGHT: Week 2, Thursday
GRADE LEVEL: 9th
· Students will keep a daily record of any physical activity they participate in, as well as everything they eat. They will use these records to investigate how many calories they are burning off doing these activities.
· By completing this activity the students will be able to calculate how many calories they are burning on a daily basis. They will also calculate the percentage of calories they are burning.
TEKS
§111.32. Algebra I (One Credit).
(a) Basic understandings.
(4) Relationship between equations and functions. Equations arise as a way of asking and answering questions involving functional relationships. Students work in many situations to set up equations and use a variety of methods to solve these equations.
§115.32. Health 1, Grades 9-10
(b) Knowledge and skills.
(1) Health information. The student analyzes health information and applies strategies for enhancing and maintaining personal health throughout the life span. The student is expected to:
(B) examine the relationship among body composition, diet, and fitness;
(I) describe the importance of taking responsibility for establishing and implementing health maintenance for individuals and family members of all ages.

(4) Physical activity and health. The student applies fitness principles during a personal fitness program. The student is expected to:
(A) explain the relationship between physical fitness and health;
(B) participate in a variety of activities that develop health-related physical fitness activities including aerobic exercise to develop cardiovascular efficiency;
(5) Physical activity and health. The student comprehends practices that impact daily performance, physical activity, and health. The student is expected to:

MATERIALS LIST and ADVANCED PREPARATION
1. http://www.prevention.com/caloriecalc/0,5719,s-4-121-48-1158-1,00.html? (Calorie calc.)
2. Diet Analysis + version 6.1 (computer program)
Outline of lesson:
- Students will be keeping a journal of calories eaten for each day for 5 days.
- They will also keep a journal of any physical activity they participate in and for how long (duration).
-After the week, they will bring their journals to class and we will discuss how to calculate how many calories they have burned, as well as the percentage of calories burned in that day.
- They will use their food intake record to find how many calories they have eaten for that day.
- They will use the diet analysis program to do this
- The program has a database of over 5,000 foods and their nutritional values.
- After inputting the foods they ate into the program it will tell them exactly how many calories they have eaten for that day.
- After they have their caloric intake for each of the 5 days they will now go to the link provided above and find out how many calories they have burned.
- They will use this site to find the exercise activity they participated in, enter the duration of time, and their weight. The site will then calculate exactly how many calories they burned doing that activity.
- Now they have a daily record of how many calories they ate, and how many calories they burned.
- As a class we will discuss how we can figure out the percentage of calories burned for each of the 5 days.
- Students should figure this ratio: amount of burned calories x 100
Total caloric intake
- After they have figured out the formula we can work some problems!
Examples of math problems:
1. Adam likes to eat at Wendy’s and he has accumulated a caloric intake of 3,629. Fortunately, he’s a big 205 pound Football player so for each hour he practices he burns 745.5 calories. If he practices 2 hours a day how many calories will he burn? What percentage of calories does he burn working out? After working off these calories, how many calories is he left with at the end of the day?
2. Erica wants to burn 20% of her calories a day. She tries to eat healthy and only eats the recommended 2,000 calories a day. How many calories does she have to burn in order to meet her goal?
3. Maria and Christy are both big health nuts. Maria burns 250 calories in 1 hour, while Christy prefers another workout where she burns 215 calories an hour. Maria works out for 2.5 hours per day and Christy works out for 3 hours a day. Maria’s daily caloric intake in 2,140 and Christy’s is 2,000. Which girl burns a higher percentage of calories in 1 day?
4. Monica had brittle nails and her doctor recommended that she increase her calcium intake by 40%. If 1 cup of milk ha 30% of the daily value for calcium, how much milk should she drink to follow the doctor’s orders?
MATH CONNECTION:
This investigation has the students record their own caloric intake and calculate the percentage of calories burned in that given day.
