Many people record and track the number of calories they consume daily since an increasing amount of tools and apps have become available. It seems like everyone knows the exact number of calories they should consume and burn per day. Why are they tracking calories? Why are calories important to your body? Through this lesson, my students discovered how important calories really are.
I posed a number of questions for my students to ponder. What is a calorie? How many calories do you consume? How many are you supposed to consume? How many calories does an Olympic swimmer consume? How many calories does an Iditarod sled dog consume? The objective of this lesson was for students to compare their caloric intake to that of an Olympic athlete and Iditarod sled dog. The results were very interesting.
This lesson required students to reflect about what they eat and drink during a day along with any exercise achieved. We started out by discussing what a calorie is and the importance of calories. A calorie is a unit of energy. Any physical activity requires a great deal of energy. Our body, and a sled dog’s body, needs energy to build and keep muscle. The students were to keep this in mind as they were working on the activity.
After calculating the amount of calories they think a person their age should consume during a day they went online to find out. They were fairly accurate. Next, it was time for them to really reflect on their health. We used an app called Diet Diary to record an entire day’s worth of eating and drinking. The students also recorded any exercise they completed. The idea behind this is to notice how many calories they truly consume along with how many they burn.
The task for the students was to create a Prezi, highlighting the differences in caloric intake between themselves, their Olympic athlete of choice, and an Iditarod sled dog. Additionally, they would be sharing their favorite food and how much of that item it would take to reach the amount of calories each person/dog needed.
Reflecting afterwards we saw some interesting data. Some kids consumed over 4,000 calories/day. Others consumed less than 2,000. Some Olympic athletes only needed to consume 3,000 calories/day, while others need to consume over 10,000, depending on their sport. Iditarod sled dogs need to consume approximately 10,000 calories/day, too. Our discussion led us to why it is necessary for some to consume so many calories. We reviewed what a calorie is again and how much energy is required for certain sports. It was very fascinating listening to all the conversations as they found out how much certain athletes “get” to eat while performing.
