Lungometer: Vital Lung Capacity
Let’s Talk About It
With younger students, draw a large graph on the board. Label the X axis “Students.” Number the Y axis from 0 to 4,000 mL, using 500 mL intervals. Have students write their names and lung capacity measurements on “sticky” notes, and then help each student place his/her note at the appropriate level on the graph (see figure).
Older students should obtain the average value for their vital lung capacities over three trials, as shown on the Lungometer Data Sheet. After students have completed their calculations, have them graph their average vital lung capacities as described in the previous paragraph.
Discuss the class results charted on the graph. Ask, What was the highest vital lung capacity in the class? What was the lowest? How could we determine the average vital lung capacity for the entire class?
