Presentation Title: Effect of Plants on Temperature and Humidity in a Closed Environment Discipline: Biology School: Owyhee Combined School Abstract: Effect of Plants on Temperature and Humidity in a Closed Environment Marla Dick and Tarra York, Owyhee Combined School

The atmospheric increase in temperatures, often called global warming, is an important issue today. Scientists around the world are concerned about greenhouse gases. The number one greenhouse gas is water vapor. Ecosystems with many plants appear to be more humid, but are the temperatures actually higher? We wanted to see what effect plants would have on humidity and temperature levels. We set up two containers (eco-chambers), and filled each one with 100 grams of potting soil. Next, we added 50 grams of water to the soil in each chamber. We planted a green spider plant (Chlorophytum comosum) in one of the containers and left the other container without a plant. We inserted a temperature and humidity gauge in each eco-chamber and then sealed the containers air-tight. We recorded the temperature and humidity levels twice every day. The results showed that the humidity level remained the same in both containers, but the temperature in the eco-chamber with the plant remained cooler than in the one without the plant.
