Global Warming Science Fair Project

The Greenhouse Effect

The Greenhouse Effect | Science Fair Projects | STEM Projects
The greenhouse effect is caused by the absorption of heat by greenhouse gasses like carbon dioxide, water vapor, methane gases and the ozone. Too much of these gasses can cause global warming, resulting in climate and weather changes. Let's find out how different surfaces affect the temperature increase due to the greenhouse effect!


The hypothesis is that carpet grass surfaces have the least amount of increase in temperature due to the greenhouse effect.

Method & Materials

You will need to set up four jars with different surfaces - water, sand, soil and grass - and measure the temperature inside the jars over an hour.
You will need four transparent glass jars with plastic covers, four thermometers, an electric drill with appropriately sized drill bits, a box of clay, a stopwatch, tap water, sand, black soil and carpet grass.


It was observed that the jar containing water had the fastest increase in temperature and the jar containing the layer of grass had the slowest temperature increase. This proves that the hypothesis that carpet grass surfaces have the least amount of increase in temperature due to the greenhouse effect is true.

Why do this project?

This science project is interesting because it shows how different surfaces can affect the temperature increase due to the greenhouse effect.

Also Consider

Experiment variations to consider include repeating the experiment during different times of the day at different light intensity, or repeating the experiment using different sizes of containers or jars.
