Using Staying Healthy – Student Edition (Human Biology) www.ck12.org 1.2 Using Staying Healthy – Student Edition (Human Biology) 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. 4 www.ck12.org Chapter 1. Staying Healthy - Teacher’s Guide (Human Biology) 1.3 Activities and Answer Keys Activity 6-1: You Are the Food Expert PLAN Summary Students examine the nutrients in fast food and create a healthy meal. Objectives Students: X determine the nutrient levels of fast foods. X determine whether fast foods meet the RDA guidelines.

Prerequisites and Background Information No special knowledge is required. IMPLEMENT Introduce Activity 6-1 by discussing the Resource. 5 1.3. Activities and Answer Keys www.ck12.org 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.
