Activity 5D: Pulmo-Park Pom-Pom Shooter: Measuring the Effect of Restricted Breathing on Peak Expiratory Flow (PEF)

A pom-pom shooter is one of the easiest and most entertaining tools your students will ever use in science class. Students simply place a small pom-pom into the mouthpiece, and blow as hard as possible with one breath. Student “spotters” will measure the distance traveled by each pom-pom and record the information for the person using the pom-pom shooter. The process is repeated with “restriction mouthpieces” placed on the pom-pom shooter. Data is analyzed and students see, very graphically, how restriction or obstruction can affect their PEF.

Objectives: 
  • Relate distance traveled by a pom-pom after being shot through a pom-pom shooter to peak expiratory flow (PEF)
  • Explain the effect of simulated pulmonary obstructive and restrictive disorders on PEF
  • Identify independent and dependent variables
  • Formulate a hypothesis
  • Collect, tabulate, graph, and analyze data
  • Explain the difference between obstructive and restrictive pulmonary diseases and provide examples of each
