What is the greenhouse effect? How did it get this name? Set up model mini-greenhouses and demonstrate the principles of the greenhouse effect for your students. In less than one class period, the measured temperature differences in the mini-greenhouses will be dramatic and reflect the exact trend that the greenhouse effect is having on the planet Earth. The results from this demonstration will serve as a launch pad for further research and stimulate lively discussion about the significance of the world data being collected.The mini-greenhouse bottles, stopper, and reflecting flags are provided in the demonstration kit and can be reused many times. The demonstration does require three thermometers and a 200-watt light source. Teacher Demonstration Notes included.
