How Many Calories Do You Use?
Chapter 30: Digestive and Excretory Systems

Any activity you perform burns a certain number of Calories. Some types of activities use more Calories than other types. Study the data in the Calorie table. Analyze your daily activities and create your own table. Your table should have three columns: one listing your daily activities, one listing the estimated amount of time you spend doing the activity, and one for the total number of Calories used for that activity.
