What makes a gas a greenhouse gas ?
Greenhouse gases are part of Earth's atmosphere. This is why Earth is often called the 'Goldilocks' planet – its conditions are just right, not too hot or too cold, allowing life to thrive.
Heat is trapped near Earth's surface by substances known as 'greenhouse gases.' Imagine these gases as a cozy blanket enveloping our planet, helping to maintain a warmer temperature than it would have otherwise.
Gases that absorb and reemit infrared light are green house gases as shown below
from https://climate.nasa.gov/climate_resources/188/graphic-the-greenhouse-effect/
We are going to use the simulation below identify greenhouse gases.
In this pHet simulation you can observe how different wavelengths of the electromagnetic spectrum interact with different molecules of light
Instructions:
You are going to test each of the gases listed with the Infrared and visible lights
Make a table to record your findings for each of the gases listed in the simulation
Click on the Greenhouse Gases ? to add your findings to the class spreadsheet and we can identify the greenhouse gases.
Put a 1 in an empty yes column of the gas if you think it is a greenhouse gas or a 1 in the no column if it is not a green house gas.
Go to the GRAPH tab to see the class results.
