Get Down and Dirty: How Does Soil Change with Depth?
What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper? The answer, often overlooked, is: soil. With this project you can get all the dirt on soil formation, soil horizons, and the composition of different soils.

Feeding Earthworms: Do Different Diets Affect Them and the Soil They Enrich?
Interested in helping the environment, and don't mind getting dirty? In this project you get to mix it up with earthworms, soil, and various types of organic kitchen scraps. The basic idea is to set up small earthworm colonies to compost different types of food waste. You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil. This project takes a little time, but it's worth it. You'll help the environment and learn about the remarkable recycling skills of the under-appreciated earthworm.

Landscapes and Water Usage
*
Some plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less...

I'm Trying to Breathe Here! Dissolved Oxygen vs. Temperature
To survive, we need oxygen in the air we breathe. Oxygen is also essential for most aquatic organisms, but there is much less oxygen available in water than in air. How much oxygen can dissolve in water? Does the temperature of the water matter? Learn how to measure dissolved oxygen and then see how oxygen concentration changes with water temperature.

Mapping Troposhperic Ozone Levels Over Time
Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, i.e., the air that we breathe, it is harmful to health. In this project you can use data from EPA monitoring stations to analyze the weather/climate conditions that can lead to harmful ozone levels.

A Matter of Degrees: How Does the Tilt of Earth's Axis Affect the Seasons?
Many people are surprised to learn that the season's we experience—winter, spring, summer and fall—have nothing to do with the distance of Earth from the Sun. In this science fair project, you will investigate how the temperature on Earth actually depends on the tilt of Earth's axis of rotation.
