Gas Laws:Hands-on Discovery

Welcome!


Who is cpo science

Developer and publisher of inquiry-based science curriculum and hands-on materials

How many have heard of CPO Science?

Sample materials at your table – PLEASE LEAVE FOR OTHER WORKSHOPS – WE CAN MAIL SAMPLES – Thanks very much!

Who is CPO Science?


How is cpo science different

We design and manufacture high quality science equipment and INCLUDE IT with purchase of textbook sets

We support guided inquiry through extensive teacher support material and reader-friendly texts

We offer strong science content that is a blend of conceptual and quantitative approaches.

How is CPO Science Different?


What subject areas

High School: Physical Science, Earth/Space Science, Physics First, CP Physics

Middle School: Earth, Life, Physical

What is a kpa or kilopascal

What is a kPa, or kilopascal?

  • A pascal (Pa) = 1 N/m2

  • 1 kPa = 1000 Pa

  • Standard atmospheric pressure = 101,325 Pa

    • Or 101.325 kPa

  • What does your pressure sensor read for standard atmospheric pressure?


Make a prediction

  • Suppose you connect a syringe to the pressure sensor.

  • What would you have to do with the syringe to make the pressure increase? How would you make the pressure decrease?

  • Boyle’s law states that there is a mathematical relationship between pressure and volume that always equals a constant value.

  • The relationship is either:


Collect data

Collect Data

  • Find the pressure at these volumes

  • 10, 12, 16, 18

  • Graph pressure vs. volume by hand

  • What is the constant value?


Predict

Predict

  • Use your data to predict the pressure at 14 mL.

  • Try it and see how close your prediction was.

Charles’ Law


Gas laws hands on discovery

How much can you change the air pressure in an empty plastic bottle by squeezing the bottle with one hand?


Gas laws hands on discovery

Explain, using Boyle’s law, what happens to the balloon inside the bottle when you pull down on the flexible bottom of the bottle.


What does this model have to do with lungs and breathing

What does this model have to do with lungs and breathing?


Gas laws hands on discovery

Predict: Does the pressure in the bottle increase or decrease when you pull down on the flexible bottom? What % change in pressure do you expect?


Gas laws hands on discovery

Use your pressure sensor and DataCollector to collect data on how the bottle pressure changes. Compare the results to your prediction.
