This activity does a few things:
- 1) is a hands-on activity
- 2) provides an opportunity to use the Vernier LabQuest and pressure sensor
- 3) is sort of fun
- 4) setup is easy, but data is pretty good
Setup
- - 3/4" PVC pipe ~ 4 foot per experiment
- - during COVID, we had only 4 groups (one person operated the LabQuest, one person "blew") collect data, others just processes the data.
- - LabQuest + pressure sensor
- - one-hole stopper with luer connector to pressure sensor
Experiment
- - with pressure sensor connected via a flexible tube to the end of the PVC pipe, one student operates the LabQuest and the other
person who blow sharply into the PVC pipe (quick blow, not extended or sustained - trying to hit a max pressure). This was repeated until the pressure exerted was relatively constant.
- - data was collected using in plot mode and the highest pressure could be read off the LabQuest.
Calculations
- - how much air did you blow into the pipe?
- - need to calculate the volume
