It is almost mid-summer! You might have colorful flowers, fresh tomatoes and yummy berries in the garden. But wait, did you remember to water them? Maybe you wonder if they get enough, too much or too little water. Should you water every day, twice a day or once a week? Should you soak the ground, or is frequently providing small amounts of water better? Unfortunately, there is no general rule, because much depends on the type of soil. In this science project, you will see how much water… Read more

Factors that Affect the Transfer of Force through Saturated Soil

Science Fair Project Idea

Scientific Method

Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail. Is there a way to prevent soil liquefaction? Do you think adding certain materials to… Read more

Geology and Energy Resources

Science Fair Project Idea

Scientific Method

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum… Read more

Geomagnetism

Science Fair Project Idea

Scientific Method

What is geomagnetism, and how does it affect the earth? Visit the USGS Geomagnetism program for more information about this invisible force (USGS, 2006). How is the earth's magnetic field patterned? Are the magnetic poles located at the exact North and South Pole? How can the fields be mapped on the Earth's surface? What is declination? Use the mapping tools to study changes in declination patterns over time. (USGS, 2006) Read more

Porosity

Science Fair Project Idea

Scientific Method

Soils are made of particles of different types and sizes. The space between particles is called pore space. Pore space determines the amount of water that a given volume of soil can hold. Porosity is the percentage of the total volume of soil that consists of pore space. Compare the porosity of different types of soil. Which types of soil hold the most water? Can you see this under a microscope? Read more

Porosity and Particle Size

STEM Activity

Have you ever heard the expression, "solid as a rock"? As it turns out, rocks are not entirely solid. Rocks actually have tiny pockets of air inside them. This is obvious when you look at a piece of volcanic rock (often called basalt), which is full of visible holes. But dense rocks, such as granite, have tiny air pockets inside them, too. These pockets of air are just much smaller. If you picked up one volcanic rock as well as one granite rock of the same size, you would notice they don't… 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 Science: How Moist is that Mud?

STEM Activity

Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle-deep in mud? Yuck! 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 the soil can help you determine how dry or wet it is. Read more
