Different Types
of Soils
The second grade class has been learning about different types of
soils in their Earth Science Unit. We have been learning about
natural resources such as soil, sand and minerals. In the unit we
will also learn about erosion, pollution and recycling. We were
inquiring about how soils are different in a small lab experiment.
The students observed the difference in potting soil and sand.
First we looked to see how they felt, looked and smelled. After
those observations we used our small hand magnifying glasses to get
a closer look at the soils. In the end of our observation we added
a small amount of water to each of the soil samples and observed
the changes made by the liquid. Our results were that both soils
were made of tiny particles. The sand was coarser, lighter in color
and absorbs water more slowly than the potting soil.
