- review healthy behaviors;
- choose one of their own behaviors they'd like to change or improve; and
- write a letter to themselves pledging to make that change, detailing why it's important to their health and outlining how they might enact the change.
- Computer with Internet access
- Print and online resources about healthy behaviors (exercise) and dangerous and unhealthy behaviors (smoking, taking drugs, drinking alcohol)
- After watching the video, ask students: How would you describe a healthy person? Write their answers on the board. Possible answers include
- exercises often,
- eats healthy foods,
- doesn't eat a lot of junk food,
- doesn't do drugs, and
- talks about their problems with someone.
- Ask students to write down an aspect of their lifestyle that they'd like to change or improve-for example, "eat a healthier diet" or "get more exercise." Then, have them to list one or two specific ways they could make that change-for example, "eat five fruits and vegetables every day" or "take walks after school, at least three times a week."
- Explain that they're going to research the lifestyle aspect they'd like to change and then create an action plan in the form of a letter to themselves.
- Once students have chosen a lifestyle aspect to change, give them this list of questions to address in their letter:
- What aspect of your health would you like to improve?
- Why is this change important to your health? What could happen if you don't make this change?
- What behavior do you need to modify? Explain one or two specific behavior changes you can make.
- Imagine how changing this habit would improve your life.
- Have students use print and online resources in their research. These Web sites contain helpful information:

- Because students' letters may be personal, you shouldn't share them with the class. Instead, ask students to pull a few lines or a short paragraph that they believe might motivate another student wishing to change the same habit. Tell them that these quotes will be anonymously posted on a "healthy habits" board.
