Soil Scientist

Soil scientists study one of our greatest natural resources—the ground beneath our feet! Soil scientists help us solve problems, like how to grow as much food as we can without damaging the soil. They determine whether the soil in an area can support a new building. They propose ways to stop erosion and flooding.

Did you know that soil scientists sometimes work with archeologists and paleontologists, to find old ruins and dinosaur bones?

One cup of soil can have more living things in it than the number of people on Earth.

Just 1 inch of the top layer of soil can take more than 500 years to form.

STEM Task:

Place three books on different objects from your classroom, such as a cushion, a roll of paper towels, a ball, or a backpack. Imagine the stack of books ¡s a building and the objects are soil. For each object, first measure the thickness and then measure it again after the “building” is placed on it. Find the difference for each set of measurements. Check to see how stable each “building” is. Record your data. Then use your data and observations to decide which object worked best.
