Assign Mini Activity: Your Target Heart-Rate Zone.
Discuss results of Mini Activity: How Much Sleep Do You Need?
Assign Mini Activity: Sources of Stress.
Assign Activity 6-1: You Are the Food Expert.
Draw students’ attention to the key ideas using means such as posters and overhead transparencies.
Select appropriate Projects to complete if time permits.
Use the Apply Your Knowledge and Review Questions in reviewing the section.
Is a taste for particular foods something you are born with or something you acquire from your family and culture?
What Do You Think?
Your Target Heart-Rate Zone Students calculate their target heart-rate zone.
How Much Sleep Do You Need? For two weeks students keep track of how much sleep they get and note their
physical and energy levels for each day. They then check to see if there is a correlation between amount of sleep and
energy level.
Sources of Stress Students make a list of things that cause them stress and how they handle stress. They analyze
their lists to suggest ways to reduce their stress.
Using your knowledge of the digestive system, think of a slogan that promotes keeping your digestive system healthy.

Steps 1-2 After students have filled out Tables A and B, ask the question “Why does Table B reflect healthier choices
than Table A?”
Give Table A to a group to fill in using a particular fast food chain’s information with instructions to choose the
worst combinations of food. Then trade Activity Reports with another group along with the fast food information
and the challenge to make the choices the healthiest possible.
Helpful Hints
• This activity works best when students are able to choose from various fast food chain menus.
• Encourage students to choose the “worst” food combinations for Table A.
ASSESS
Use the completion of the chart and written responses on the Activity Report to assess if students can
X determine the percentages of calories (Cal) from carbohydrates, proteins, and fats in fast foods.
X determine whether fast foods meet the RDA guidelines.
