Greenhouse Gases

Lab Summary

Use a fast response temperature sensor and an EcoChamber to determine the effect of a man-made organofluorine compound, a greenhouse gas, on the trapping of heat in an isolated system.

Theory

Determine the effect of a man-made organofluorine compound, a greenhouse gas, on the trapping of heat in an isolated system. During this investigation, students:

  • Reproduce and study a greenhouse gas environment.
  • Describe the relationship between the type of gas in a system and its ability to absorb energy.
  • Consider the impact of human-made solutions to global warming and ozone-depletion.

Method

Students gain experience conducting the following procedure:

  • Simulating a greenhouse gas environment using difluoroethane

Sensors / Equipment Used:

Advanced Water Quality Sensor

(PS-2230)

MultiMeasure sensor that incorporates pH, conductivity, temperature, and the optical dissolved oxygen probe.

EcoChamber

(ME-6667)

A single acrylic chamber designed to integrate sensors for controlled-environment experiments such as fermentation and plant or cricket respiration.

Materials Used:

Balance - 1 per class
Canned keyboard duster (fresh) 
Dark aquarium rocks or dark sand ~200 g
Heating lamp 
Heavy-duty tape 
Ring stand 
Size 5 or 5 1/2 solid stoppers - 2
