Today my class completed a new science project.
As groups, we were to examine each of the four soil components and to see what would happen if we dropped them in water. The four soil components were sand, gravel, clay, and humus. Since two of the kids in my group were on vacation, it was just me and Luke. Ms. Papantoniou handed out a packet for us to write down our observations. The first questions were about the appearance and texture. The bottom ones were about when we put it in the water. My favorite soil to put in the water was the humus because some of it floated, and some fell to the bottom of the cup like snow. When Luke stirred the humus, it looked like black ink.
With experimenting each of the four soil components I learned something new. With the gravel, I learned that it was the first one of the soil components to drop because it was heavy. With the clay, I learned that it can be both big and small, some of it can dissolve into the water, and it can clump together. With sand, I learned that it turns the water cloudy, when you drop it in the water. And for the humus, I learned that it floats on water, it falls down from the top of the water like snow, some of it can dissolve into the water, it clumps together, and it turns the water black like ink.
