Question

Inquiry-based Lung Vital Capacity Lab Purpose: When you inhale, air rushes into your lungs. The amount of air that rushes in during a normal breath is called the tidal volume. Your lungs have the capacity to accept a much larger volume of air than you normally inhale. For example, you might be asked to take a deep breath during a medical exam. Scientists use the term vital capacity to describe the largest volume of air that you can exhale after you take a deep breath. Hypothesis: If I complete all three test, then I will have the greatest lung capacity while standing. Estimating Vital Capacity Research has shown that vital capacity is proportional to the surface area of a person's body. You can estimate your surface area if you know your height and your mass. 1. Convert your height in inches to centimeters by multiplying the number of inches by 2.54. 172.72 2. Convert your mass in pounds to kilograms by multiplying the number of pounds by 0.454. 59.02 3. Use Figure 1 to estimate the surface area of your body. Find your height on the scale on the left. Find your mass on the scale on the right. Use a ruler to draw a straight line between those points. The location where the line crosses the middle scale is your estimated surface area. Figure 1 Estimated surface area
