Earth Science Projects For Intermediate Levels

Which Materials Insulate Best Against Windchill?
The windchill factor is not an actual temperature, but a measure of how quickly heat is lost from an object. Experiment with different materials to check out which ones protect water exposed to wind.
For reference: Revised Wind Chill Index, Convection
Do Clouds Tell Us What Weather Is Coming?
Observing clouds can tell us a lot about what kind of weather to expect. The experiment described in this section will help you to know what to look for when using clouds to predict upcoming weather.
For reference: Clouds and Cloud Formation, Ten Major Cloud Types, Cloud, What Kind of Cloudy Is It?
Solar Hot Dog Cooker
Instructions on building a solar-powered hot-dog cooker.
For reference: Solar Energy
What Factors Most Affect Evaporation?
Experiment to test the different factors that affect the evaporation rate of water.
For reference: Evaporation, Potential and Kinetic Energy

Earth Science Projects For Advanced Levels

How Can Different Polymers Be Identified?
Examine six types of plastic and make comparisons between all of them. Can you differentiate between various types of plastic, based on their physical and chemical properties?
For reference: Plastic, Polymer, The Three R's of the Environment, User's Guide to Environmental Language
How Much Oxygen Is in the Air?
You can test how much oxygen is in the air by making a controlled environment and using a common material to pull the oxygen out of the air.
For reference: The Atmosphere, Nitrogen, Oxygen
Which Is More Acidic, Snow or Rain?
You can measure the acidity of rain and snow in your area using the pH scale and pH paper to find out which is more acid.
For reference: Acid Rain, pH, The pH Scale
