Forced Vital Capacity Science Fair Projects

Human health science fair projects develop new connection between second hand smoke and student health...

Second Hand Smoke

What is second hand smoke? It is the exhaust and byproducts of cigarettes and cigars.

Objectives/Goals

My objective was to determine whether living with a smoker or non-smoker affects your forced vital capacity.

Methods/Materials

1. Gather all necessary materials needed for the experiment.
2. Select students to get tested.
3. Make sure that the students understand, fill out, and return the survey.
4. The selected students will get tested with the Spirometer.
5. Record name, age, gender, height, and weight of each student.
6. Turn on the spirometer. Insert the subject's details; age, height, weight, and gender. Insert a mouthpiece to the head house of spirometer and make sure it is tightly fitted. Apply nose clip on subject. Have the subject lean forward and insert the mouthpiece to their mouth and have them hold the spirometer with one hand. Press FVC symbol to start the test.

Results

From my experiment, I found that for 6th grade, they had the least amount of students living with smokers so they had the highest forced vital capacity. For 7th grade, they had the mid-range of students living with smokers, but they had the lowest forced vital capacity. Finally, for 8th grade, they had the highest amount of students living with smokers, but they had a mid-range forced vital capacity between the other two grades.

Conclusions/Discussion

By doing this experiment, I found that my hypothesis was partially right. I learned also that many other factors that can easily change my results and the results can change from a day to day basis. It also helped me learn about social/behavioral science because most students with an exception of a few lived with smokers and interact with them that it can be harmful to their health. 3rd party contributor
