Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle deep in mud? Yikes! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science activity you will investigate whether the color of soil can help you determine how dry or wet it is. Read more

Have you ever noticed how much work it is to dig a hole in really hard soil? It's much easier to dig a hole in soft, loose soil. But why is that? Soil that is hard and dry is often compacted, which means that it has been packed down, making it denser and thereby difficult to penetrate. Soil that has become compacted is not only harder for you to dig a hole in, but it can also be much harder for a lot of other organisms, such as helpful earthworms, to survive in. Read more

Soil Structure

Science Fair Project Idea

Scientific Method

What variables contribute to the properties of the soil in an area? Investigate the role of climate, weather, topography, time, parent material, vegetation, and biological and chemical agents on soil formation. How are soils characterized? There are 3 basic particle sizes which create three basic soil types: sand, silt, and clay. Investigate the properties of the three different types of soil by observing grain size, shape, hardness, color, chemical composition, pore space, aeration,… Read more

Speleology: Counting Formations in a Local Cave

Science Fair Project Idea

Scientific Method

Caves have been used for much more than just exploring throughout Earth's history. Caves have been used for shelter, for religious purposes, and for burial sites. They were even used for food storage, before refrigeration, because they are cool and have constant high humidity. But how are caves formed? What causes those fantastic formations in caves? How do cave formations change as you go deeper in the cave? Get ready for an adventure as you visit a local cave and learn more in this science… Read more

Under Pressure: Sand Under Lateral Compression

Science Fair Project Idea

Scientific Method

Here's a project that involves a different kind of sandbox than the ones you usually think of. This one has a moving wall inside, acting like a piston, to compress the sand. You can make layers using two different colors of sand, and then see what happens when you compress the layers with the piston. If you're handy with woodworking tools, this is a good project to give you a feel for the effects of geological forces that deform the Earth's crust. Read more

Underground Water Flow and Darcy's Law

Science Fair Project Idea

Scientific Method

This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. Read more
