Global warming is an environmental science topic of much concern. The average surface temperature the Earth increased by 0.6ºC during the 20th century, with the increase occurring mainly from 1910 to 1945 and 1976 to 2000. The 1990s was the warmest decade, and 1998 was the warmest year of the century and on record. Growing scientific consensus attributes this global warming to the enhanced greenhouse effect. In this experiment you and your classmates will investigate the greenhouse effect and the enhanced greenhouse effect.


In the Preliminary Activity, you will gain experience using a Temperature Probe and learn technique that can be used in your subsequent research.

After completing the Preliminary Activity, you will first use reference sources to find out more about global warming, the greenhouse effect, and the enhanced greenhouse effect before you choose and investigate a researchable question.
