Cautiously sticking a finger in each of four bowls — sand, silt, clay and a combination of the three — students quickly discovered some differences in the types of soil.
Third-graders in Jared Selover’s class at Wapakoneta Elementary School worked on several different experiments on Tuesday as they wrapped up a science unit studying soil.
As they learned about the different types of soil, Selover said they discovered different properties of the soils, including which held water and which could support roots, and that ultimately a combination of all the different types makes the best soil for plants and animals.
“Water goes through the sand, the clay is too slippery

and the roots can’t hold on, a combination is the best so plants grow,” Selover said.
Students also learned about topsoil, subsoil and bedrock.
They recorded their findings on which types of soil filtered water and how much water the types of soils held on charts after the experiments were done.
The second week of studying soil, the students got to experience the differences in the types of soils hands on with the experiments before they were tested on them.n
“Hopefully it gives them an activity they can relate to and remember later,” Selover said.
