Second graders know that some soil types are better than others. They also know that there are stronger, more stable solutions to keep a structure in the earth. But what happens when the soil we have at a site isn't the strongest? How can we change it to make it stronger?
Using clay as a model for soil particles, second graders saw how compacting the soil changes the soil's shape and structure. Compacting the soil means to push down on it.
