Activity Overview
In this activity, students' will use a pressure sensor to investigate the relationship between pressure and volume for an enclosed air sample, and fit an inverse function model to the pressure versus volume data.
Before the Activity
Connect the pressure probe to Channel 1 on the CBL 2™ or Vernier LabPro® unit
Connect the CBL 2 or LabPro to the calculator using the Unit-to-Unit cable
See the attached PDF file for detailed instructions for this activity
Print pages 145 - 153 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Prepare the pressure sensor and an air sample for data collection
Attach the syringe to the pressure sensor
Move the piston in the syringe and collect pressure data for different volumes of air in the syringe
Examine the pressure versus volume graph
Plot pressure versus inverse volume values and determine the modeling equation
After the Activity
Students' will complete the Data Collection and Analysis Sheet and answer questions listed in it.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
