  1. Yawn… An investigation in the cause of one of science’s most debated topics.

  2. What’s Your Problem? Problem Statement: What causes yawns in humans?

  3. Take a Wild Guess Hypothesis: If the environment created an atmosphere of boredom, then the number of yawns would increase, because yawning is a psychological response to a lack of stimulation.

  4. It Depends… Independent Variable: Environmental stimulation (or lack thereof) Dependent Variable: Number and/or rate of yawns

  5. What do we need? Materials: • Students ages 12-14 • An article that is described as boring by middle school students

  6. How Do You Do It? Procedures: • Write a permission slip and distribute it to students. • Record yawns of students during 15 minutes during a class taught by Ms. Orsi. • Read an exceedingly boring article 3 minutes in length to a class. Observe yawns. • Have students jog in place for 1 ½ minutes. Record yawns.

  7. And the Results… Data: Qualitative and Quantitative: Where’s the tables? Well, the tables themselves have 24 rows, which would not fit on a PowerPoint, so I have included simplified versions with total numbers of yawns for the class for each variable and general statements for observations. (skip to next slide.)

  8. And the Results… Data:

  9. And the Results… Data:

  10. Explain, Please Summary of Data:

  11. Wrap it Up Conclusion • The question: “Why do we yawn?” The answer: as a reaction to boredom. The data supported the hypothesis quite distinctly.. Boredom caused more yawns because yawning is a psychological reaction to lack of stimulation, much like crying is one to sadness, and smiling is one to happiness. The procedure had to change a bit. The amount of jogging the students did had to be decreased, as the originally planned 3 minutes was a bit much. Also, the article had to change, as the original went missing.

  12. Wrap it Up (cont.) • A similar project could be whether smiling can affect your mood so that you feel happy, or whether yawns are contagious or not. • This project applies to the real world because when teachers see their students yawning, they can realize that the students aren’t’ understanding, or aren’t interested, and can do something about it. .
