Review for:Gas Pressure SensorIf you used this resource in your own classroom, please add your review. posted: on December 18, 2006 at 2:36PM
My rating of this resource: ****
My experience using this resource: Physics
Topic I was teaching: Pressure & volume  Boyle's Law
My learning goal for which this resource was used: To examine the relationship between volume and pressure of a gas
Course Level: Intro or Regular, Remedial
How I/my students used the resource: Changed the volume in the syringe and the LabPro recorded the pressure values. Students answered the following questions:What happens to the pressure of the gas as you increase the volume of the syringe? Compare the pressure of the gas at volumes of 5 and 10 mL, 6 and 12 mL, 7 and 14 mL, etc. What happens to the pressure when you double the volume? What would the pressure be at 40 mL? Explain how you know. Do pressure and volume vary directly or inversely? Explain. Boyle's Law states that P1V1 = P2V2. In other words, Pressure x Volume is a constant. Did you find you find that your values for PV were roughly the same for each measurement?
Value Added: Provides visualization or animation, Increases graphing skills, Increases data collection & analysis skills, Provides practice or tutorial, Provides additional content, Increases student engagement and motivation
Strengths: Kids have a great time! Instant access to graphs & data. Great visualization tool for the students. Once the computers and sensors are set up, it actually works pretty well.
Weaknesses: Can take several hours to get the laptops and sensors up and running the day before.
