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.
